  • New MICRON3D green stereo industrial scanner

    The NEW MICRON3D green stereo industrial scanner will be presented for the first time on the British market during the TCT Show in Birmingham, UK 24-26 September 2019.

    Two detectors, measurement with green LED light, total noise reduction, the ability to perform professional 3D scans independent of changes in external lighting conditions... are the main features of the latest product created by specialists from SMARTTECH3D company. MICRON3D green stereo is a revolutionary optical measuring machine dedicated to modern enterprises.

    The best specialists from the SMARTTECH3D company was working for over two and a half years to create an innovative 3D scanner that, thanks to its properties, perfectly fits into the assumptions of the idea of ​​industry 4.0. It is also a response to the demand from the industrial sector, which expects modern quality control devices. That is why SMARTTECH3D has developed a method of measuring with green LED light with a wavelength of 520nm, which, together with the filters used, reduces the impact of lighting changes on measurements. Thanks to this, we can get results up to 30% better than the traditional method of measuring with white light.

    What additionally distinguishes the MICRON3D green stereo scanner among the offers on the market is the use of high-quality two monochrome detectors, which allows for a more accurate representation of the structure of the scanned surface. Each object is scanned in Stereo Mode: from two independent directions at the same time, and the measurement result is a registered common part. The new projection method included in MICRON3D green stereo - Double Directed Stripes (DDS) means that the light stripes are now projected at each object perpendicularly – as were used in previous models and horizontally which is the novelty. Stereo Mode and DDS projection method technology results in lower uncertainty of scanning results, lower number of errors and noise reduction in scanning results.

    The shockproof carbon-fibre cover is temperature resistant while HAPA filers preserve it from dust.

    The MICRON3D green stereo scanner is dedicated mainly to the industrial sector and thanks to its properties it is ideally suited to quality control or reverse engineering.

    The latest SMARTTECH3D scanner will be presented for the first time on the British market during the TCT Show in Birmingham on September 24th-26th, 2019.

    We also invite you to the official lecture at the TCT Introducing Stage, which will take place on September 25th at 15:00. Our products will also be available at stand number E35.

  • Catalysis Application Note

    CO2 Electroreduction

    CO2 electroreduction is a promising technology that uses intermittent renewable electricity and CO2 emissions to product fuels (e.g. methanol) and other economically relevant products (e.g. syngas). One of the great promises of this technology is to recycle the CO2 produced by factories, reducing CO2 emissions and its impact to climate change.

    In order for CO2 electroreduction to play a major role in the energy transition, the main components of a CO2 electroreduction device, the electrocatalysts, need to be optimised to produce fuels or chemicals efficiently and selectively.

  • AN-117 Measuring Insertion Loss and Return Loss of Hybrid Cables in OPL-MAX

    Obtaining connector-level insertion loss (IL) and return loss (RL) for hybrid cables is complicated by the different connector types on either end of the cable. Hybrid cables cannot simply be flipped to test the reverse direction when the reference and device under test (DUT) connectors are no longer compatible. A test setup comprised of the OP940 IL and RL Meter with two detectors, the OP725 Benchtop Optical Switch, and OPL-Max Application Software solves the compatibility issue and allows for hybrid cable testing with high speed, accuracy, and repeatability.

  • How Can You Accurately Test Performance of Hybrid Cables?

    Fibre patch cables, also known as patch cord or jumper cables, are fibre optic cables that are terminated with connectors on both ends. When the connector types on each end are different, the cable is aptly dubbed a HYBRID CABLE. These hybrid cables can serve to link otherwise incompatible infrastructure in existing fibre systems, such as those found in networks or data centres. They can be used to connect newer racks to legacy hardware, in distribution hubs to branch lines from high density panels to the nodes they serve, or to connect between devices from different manufacturers.

    How Can You Accurately Test Performance of Hybrid Cables?
    While the hybrid nature of these cables makes them ideal for these types of applications, it does present some challenges when evaluating the performance of the cables, whether during production or prior to installation. Like most other passive components that are added to networks or data centres, hybrid cables typically need to have both sides qualified for insertion loss (IL) and return loss (RL), along with interferometry and visual inspection.

    The challenge comes from mating the different connectors of the hybrid cable to the reference cables and detectors used to measure IL and RL, which must be done since each side of the cable must be tested. This can be achieved by having twice as many reference cables and detectors, two of each in the case of a simplex cable.

    Tailored Solution for a Challenging Problem
    The OP940 IL and RL meter serves as the base for our simplex hybrid cable test system, built with two detectors to accommodate the different connectors. Introducing the OP725 optical switch allows us to use two reference cables by toggling which cable the light travels through.
    This configuration provides both ease of use and flexibility. Having multiple reference cables connected at once allows the user to test both sides of the device under test without having to swap cables in and out. This particular example uses LC and SC cables, but testing different connector types is as simple as substituting different reference cables. A similar substitution can be done for the adapters on the detectors. In fact, if the different connectors have the same size ferrule (i.e. FC and SC), the configuration can be simplified to use one detector with a universal adapter.

    A Note on Hybrid Mating Adapters:
    While hybrid mating adapters can allow different connector types to be mated together, these types of adapters can cause issues for IL testing. LC to SC mating adapters in particular often induce extra loss into the measurements. The difference in ferrule size between the two connector types makes their connection within the hybrid mating adapter unreliable for IL testing. For this reason, the better approach is to use a different reference cable for each type of connector being tested.

  • The 3D scanner in a unique design for creating an anatomical baby bottle

    Today, the accessory industry for newborns and infants is a dynamically developing business sector. Manufacturers compete to invent increasingly sophisticated and creative products designed to help young parents in caring for their children. Among the many colourful and often unnecessary products, there are exceptional products that are designed to really help and support parents to create normality where it’s not always possible.

    A bottle of the future
    One such unique product is the personalised “New Eve” milk dispenser. Created by designer Beata Nikolajczyk - Miniak, it has been awarded many times in various prestigious competitions. The design of this innovative baby milk bottle is the shape of a female breast. It’s designed this way to reproduce the experience of natural feeding in situations where it is not always possible. It was created on the basis of research supported by the financial resources of the Ministry of Science and Higher Education.

    The process of creating a bottle started with a questionnaire dedicated to mothers feeding naturally, distributed on social networks and made available in various charitable institutions. The study involved 100 women whose breasts were sized on the basis of collected data from two angles - front view and a cross-section view. The irregular shape of the female breast was able to be reproduced using the most modern 3D scanning technology within the new SMARTTECH3D scanner. The scanner operates with structural white LED light technology and measures a field of 300x200mm in only 0.2 seconds. Because it’s using light, the measurement is completely safe for the human body.

    3D scanning itself involves obtaining information about the shape, and geometry of an object and creating its virtual digital copy. As a result of scanning, a cloud of points is obtained,  meaning a set of reflecting surfaces of the scanned object. They are described by three X, Y, Z coordinates and can also store object colour information. Then a triangle mesh is created from these points. Thanks to this, the shape of the object is reflected in detail using a set of several million small triangles.

    Gathering data about the shape of the nipple was done using only the 3D scanner, which was able to take the geometric dimensions: width, length, and height of the nipple. Using SMARTTECH3Dmeasure, a detailed analysis was able to generate precise calculations of the examined surface including indentations, inequalities occurring on the nipple surface and it was also possible to see an enlarged view of the nipple-areola surface.

    Warmth, closeness, and security enclosed in the shape of a mother's breast
    Averaging the results and analysing the relationship between the proportions of individual parts of the breast collected from all the tests on the nipple measurements contributed to the formation of the bottle in the shape closest to the natural breast. Observation of the nipple itself helped to design the shape and structure of the element responsible for the outflow of milk.

    This research was how the revolutionary "New Eve" milk dispenser was created, which has both the anatomical and sensory features of a mother's breast. Apart from being a similar shape, “New Eve” mimics the colour, feeling, and even temperature of a natural breast, by integrating a heating element. In the construction of the dispenser, a material of variable thickness was used, which is thinnest and most flexible near the nipple, but thicker at the base which also helps to dissipate heat. The feeling of the milk temperature in the dispenser is also directly related to its shape, which allows the newborn to comfortably cuddle to the larger surface of the "warm breast". The "New Eve" milk dispenser is a revolutionary project in the baby products industry and will certainly find a wide range of interested recipients. It would not have been created without the use of 3D scanners, which helped most accurately reproduce the ideal shape of a woman's breast.

    The bottle design itself has already been awarded many times at both the national and international competitions. This project, among others, was a finalist in the international contest make me! organised by Łódź Design Festival - one of the most important international competitions for designers of the young generation. In addition, the bottle was noticed by the world-class jury in the Red dot competition and qualified for the finals.

  • SXRTO Oscilloscopes Explained

    Pico Technology have launched their latest 5 GHz SXRTO Sampler Extended Real Time Oscilloscope, but what is SXRTO. Learn more about the benefits and cost savings compared to Real Time Oscilloscopes, RTO below.

    The real-time oscilloscope
    Real-time oscilloscopes (RTOs) are designed with a high enough sampling rate to capture a transient, non-repetitive signal with the instrument’s specified analogue bandwidth. According to Nyquist’s sampling theorem, for accurate capture and display of the signal the scope’s sampling rate must be at least twice the signal bandwidth. Typical high-bandwidth RTOs exceed this sampling rate by perhaps a factor of two, achieving up to four samples per cycle, or three samples in a minimum-width impulse.

    Equivalent-time sampling
    For signals close to or above the RTO’s Nyquist limit, many RTOs can switch to a mode called equivalent-time sampling (ETS). In this mode the scope collects as many samples as it can for each of many trigger events, each trigger contributing more and more samples and detail in a reconstructed waveform. Critical to alignment of these samples is a separate and precise measurement of time between each trigger and the next occurring sample clock.
    After a large number of trigger events the scope has enough samples to display the waveform with the desired time resolution. This is called the effective sampling resolution (the inverse of the effective sampling rate), which is many times higher than is possible in real-time (non-ETS) mode.
    As this technique relies on a random relationship between trigger events and the sampling clock, it is more correctly called random equivalent-time sampling (or sometimes random interleaved sampling, RIS). It can only be used for repetitive signals – those that vary little from one trigger event to the next.

    The sampler-extended real-time oscilloscope (SXRTO)
    The PicoScope 9404 SXRTO has a maximum effective sampling rate in ETS of 1 TS/s. This corresponds to a timing resolution of 1ps, 2000 times higher than its actual maximum sampling rate.
    The PicoScope 9404-05 SXRTO has an analogue bandwidth of 5 GHz. This means that it requires a sampling rate of at least 10 GS/s, but for an accurate reconstruction of wave shape, we need far higher than this. The PicoScope 9404 gives us 200 sample points in a single cycle at 5 GHz and 140 points in a minimum-width impulse.

    So is the SXRTO a sampling scope?
    All this talk of sampling rates and sampling modes may suggest that the SXRTO is a type of sampling scope, but this is not the case. The name sampling scope, by convention, refers to a different kind of instrument. A sampling scope uses a programmable delay generator to take samples at regular intervals after each trigger event. The technique is called sequential equivalent-time sampling and is the principle behind the PicoScope 9300 Series sampling scopes. These scopes can achieve very high effective sampling rates but have two main drawbacks: they cannot capture data before the trigger event, and they require a separate trigger signal – either from an external source or from a built-in clock-recovery module.
    We’ve compiled a table to show the differences between the types of scopes mentioned on this page. The example products are all compact, 4-channel, USB PicoScopes.

    *Higher-bandwidth real-time oscilloscopes are available from other manufacturers.
    **These functions are possible at low sampling rates, up to 1 MS/s.

  • Full area topography and thickness of sub-micron films

    Precise, reliable, characterisation of thin film topography and thickness, and substrate topography.

    Thin transparent thin films are critical across a variety of markets and applications, including consumer electronics, semiconductors and optics. Precise monitoring and control of thin film processes is achieved by measuring top surface, thickness, and substrate surface characteristics – all of which are enabled by multiple thin film measurement and analysis technologies available on ZYGO's 3D optical profilers.

    In an ideal world, a surface metrology technology developed to measure submicron films will retain its performance for topography alone. This takes account of metrics, such as resolution and throughput and even the configuration flexibility. For microscope based technologies, this means that films analysis should not restrict the choice of objective or zoom.

    For thick films, the signals are well separated and can be easily distinguished between the top surface and the substrate. However, a transparent film will generally produce an additional signal from the substrate and therefore the surface and substrate signals merge and are no longer separable. But this sensitivity to films also gives the opportunity for the distorted CSI signal to be decoded to simultaneously determine surface and thickness.

    Fig1. Typical CSI signals for (a) bare surface (no film); (b) thick film (well over 1µm) with well-separated signals from surface to substrate; and (c) submicron film with merged surface and substrate signals.

    Advanced Model Based Analysis (MBA) is the most advanced CSI-based thin film measurement technique available from ZYGO, and works by comparing a theoretical model of the sample film stack to an actual measurement signal as seen by the profiler. This patented technology simultaneously measures topography, thickness, and substrate topography for single layer films from 50–2000nm in seconds. In addition to thin film characterisation, MBA technology can be used to perform true topography measurements of dissimilar materials by adjusting for the phase change on reflection (PCOR) that occurs in these situations.

    Standard Film Analysis (LSQ) is used to measure film thickness and substrates of films from 1–150µm optical thickness, as well as the top surface of films from 0.4–150µm. Thick film metrology works by isolating the interference signals that are created by the multiple material interfaces and require only basic knowledge of the film's index of refraction.

    Because they are based on CSI technology, there are several advantages that MBA and LSQ thin film measurement technologies provide compared to other techniques:

    • 3D areal surface maps provide context for understanding a process that cannot be observed when film metrology is reduced to a single thickness number.
    • Film measurement is performed through-the-lens, which helps to ensure that the region of interest is exactly the region profiled.
    • No additional hardware is required for most applications of MBA or LSQ thin film measurement.

    Standard Film Analysis (LSQ) is available as an option on NewView 9000, Nexview and Nexview NX2 profilers, while Advanced Model Based Analysis (MBA) is available as an option exclusively on the Nexview and Nexview NX2 platforms.
