Measuring Index and Thickness of Silicon Thin Films
The Metricon Model 2010/M provides rapid and accurate measurements of thin films of silicon on cladding layers of lower index materials such as SiO2 or bulk fused silica/glasses for wavelengths at which the films are transparent (typically 1100 nm and above). Convenient 30-second measurements can be made with a single prism for sample thicknesses over the 1.4 -3.5 micron thickness... -
Measuring Refractive Index of Liquids Inside Sealed Containers
Metricon’s Model 2010/M accurately and rapidly measures refractive index of liquids inside sealed containers such as glass vials/bottles, allowing rapid and non-destructive measurement of solution concentration for quality control purposes. Matching liquids are not required between the measuring prism and the wall of the container. If a label is present, the only requirement is that there be a gap of... -
A History of ZYGO Optical Profilers
Some brief notes on the systems and technology over the years: Heterodyne profiler Maxim 5700: Micro Fizeau, tip/tilt in the head, PSI (Phase Shifting Interferometry), HPUX system controllers. Maxim 3D: PSI, 2 wavelengths for rougher surfaces, HPUX system controllers. NewView 100: The first Scanning White Light Interferometer (SWLI) from Zygo, uses Frequency Domain Analysis (FDA) to achieve high resolution over... -
Energy Storage Application Note – Water Splitting
Among the solar fuel technologies, water splitting is a relatively mature technology that uses renewable electricity and water to product H₂. Storing renewable energy as H₂ is a solution for the intermittency problem of solar cells and wind turbines. Moreover, a large amount of H₂ is produced in non-renewable ways every day for important industrial processes. Replacing that H₂ by... -
Catalysis Application Note – CO₂ Hydrogenation
CO₂ capturing and utilisation technologies have the potential of decreasing the CO₂ emissions that cause climate change. Utilisation of CO₂ also allows to directly recycle the CO₂ produced in the industry to make the process carbon neutral and to produce value-added products (fuels and chemicals). Methanol is an excellent product for CO₂ utilisation, since it is already produced world-wide in large... -
Catalysis Application Note - Fuel Cells Research
Fuel cells Storing electricity into fuels is a promising way to solve the intermittency problem of solar cells and wind turbines. However, in order to start implementing renewable fuels, the conversion process from these fuels back to electricity needs to be carried out efficiently and cheaply. Fuel cells are devises that can convert a great variety of chemical fuels into... -
Catalysis Application Note - CO2 Electroreduction
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... -
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...
