We’d like to let you into a little secret…

…the Stanford Research Systems FS725 Rubidium Master clock is ideal for use in the recording or broadcast studio to improve digital audio and video quality. What is more, this proven scientific instrumentation product is available for much less than the cost of other well known pro-audio Rubidium clocks.  

For nearly 30 years Stanford Research Systems have been building a solid reputation for class leading scientific instrumentation products at sensible prices.

With exceptional accuracy (100,000 times better than a conventional crystal oscillator), superb stability and low phase noise, the basic FS725 unit provides two 10MHz sine wave outputs, one 5MHz sine wave output and a 1pps square wave output. This is expandable in the box to 14 x 10MHz, 4 x 5MHz and 4 x 1pps outputs. A rack-mount kit and additional distribution amplifiers are also available. Operation couldn’t be simpler – plug in and forget!

Using the 10MHz FS725 Rubidium clock signal as a master clock for your digital audio/video system ensures all your components have access to the uncompromising accuracy and long-term stability only atomic clocks can give. An FS725 synchronised audio/video system will minimise jitter and timing induced artefacts, and at a price that need not break the bank.

SCHOTT KL 200 LED and EasyLED Ringlight Plus bring Cold Light to Bear in Stereo Microscopy, Macroscopy and Photography Units Feature Ergonomic Controls and Low Noise. 

SCHOTT’s Fiber Optics Division released the NEW KL 200 LED Series cold light engine and the EasyLED Ringlight Plus stereo microscopy lamp. These low energy consuming lighting solutions are designed to bring high-performance illumination to industrial, biological lab, and home applications.

Both products come with integrated controllers and can be mounted directly to the microscope. This saves space on the workbench and allows for ergonomic operation, because all levers needed are part of the microscope stand. There is no need to remove eyes from eyepieces while working.

The KL 200 LED is a fiber optic cold light source that contains an LED light engine that is actually brighter than a 20 watt halogen bulb, while using 80 percent less energy (5 W vs. 25 W). Because there is no need to change bulbs on the KL 200 LED, the costs of replacing or servicing bulbs is also eliminated. The LED light engine offers a brighter, neutral 5300 K white light; continuous dimming (0-100) and a separate on/off switch. This allows users to maintain light level settings over multiple sessions.

The compact housing easily adapts to multitudes of microscope stands. Convection cooling makes the KL 200 LED a compact and versatile unit that is free of noise and vibration. KL 200 LED is designed for ease of use and conform to CSA (United States) and the CE standards. It comes with a universal power supply (120 - 240-volt) so it can be used worldwide.  

“The SCHOTT KL 200 LED offers customers both superior performance and long operational life, at a most attractive price,” said Carl VanDommelen, sales manager, SCHOTT Fiber Optics. “The long lasting LED lights, combined with the carefully designed ergonomic controls assure a long operational life in labs and other research facilities worldwide.”

The EasyLED Ringlight Plus contains 48 high brightness neutral white (5,600 K) LEDs and features an innovative “jog dial” wheel for convenient and intuitive operation. The ring-lights can be directly attached to lenses and operate over a wide range of working distances (from 50 to 130 mm). Segment-able ring-lights can emulate various fiber optic geometries like continuous ring, double gooseneck or linelights.

Images produced by the EasyLED Ringlight Plus possess excellent color fidelity and are well-suited for use with digital cameras. All units offer a universal power supply (100-240 V) and use direct current to make the EasyLED Ringlight Plus absolutely flicker-free. Separate dimming and on/off switches keep light level settings consistent use after use.

Fan-less design makes the EasyLED Ringlight Plus quiet, vibration-free, and suitable for both clean room and rougher laboratory or industrial environments. The product has a lifetime of 30,000 hours, saving both energy as well as the cost of replacing halogen bulbs. A suite of accessories, including adaptors, polarizers, protection glasses and diffusers, make EasyLED Ringlight Plus suitable for any stereo microscope.

“The EasyLED Ringlight Plus is a flexible high-precision tool, combining both excellent performance and attractive pricing,” said VanDommelen. “The innovative ‘Jog Dial’ wheel and compact low-power consumption based technology, makes the EasyLED Ringlight Plus the new standard in microscopy illumination.”

To ensure SCHOTT customers receive competent support and guidance, the new SCHOTT products will be sold via Lambda Photometrics.

The Pizzicato is an all-solid state, mode-locked picosecond Nd:YAG laser providing up to 100mJ in a 35ps pulse at 1064nm with high stability

Based on a unique design, the Pizzicato features low jitter, high pulse-to-pulse stability with synchronization capability. The all solid state design is free from the constraints of previous designs that used liquid saturatable absorbers whilst maintaining short pulse durations of 35ps.

The Pizzicato’s mode-locking device forces all the longitudinal modes of the laser cavity to oscillate in phase, allowing the resonator to generate ultrafast (picosecond) pulses.  

The picosecond pulses result from the rotation of the polarization by frequency back conversion in a non-linear crystal. This totally passive device produces a wave train made up of several ultrafast pulses and is combined with a double-pass Pockels cell pulse picker system. Together these components produce stabilized ultrafast pulses precisely separated by a few nanoseconds.    

The pulse picker generates a synchronization signal allowing the laser to be synchronized with other apparatus and produces excellent energy stability, whilst the second pass increases the energy, power contrast and aids stability & reproducibility.  

Only the highest quality mechanical, electronic, and optical components have been used in the Pizzicato to ensure high performance, trouble-free operation and ease of use throughout the laser’s lifetime. These include a carbon fibre resonator support structure with floating fasteners to efficiently absorb any differential expansion and an optical isolator situated between the preamplifier and amplifier to protect the oscillator and mode-locking module against back reflections.

Lambda Photometrics are pleased to announce two new tunable OPO laser systems from Opotek, the high-repetition rate Opolette HR and the high-energy Opolette HE.

Opolette HE

The Opolette is an integrated, turn-key tunable laser system. It is the most compact system of its kind with a footprint of only 7" x 12".

All system components, including the pump laser, the OPO, and optional UV modules are mounted on a single, hermetically sealed, optical frame.The user-friendly software provided with the system enables easy access to all the system functions.

The patented OPO is a Double Resonance Oscillator (DRO) as well as a Double Pass Oscillator (DPO), resulting in high conversion efficiency, walk-off and beam steering cancellation, and excellent pointing stability.

The Opolette is now available in a high-energy (HE) version, pumped by the Big Sky Ultra 100 which provides a peak energy of 10mJ

Opolette HR

The Opolette HR is a true solid state, integrated tunable laser system. The system incorporates the Big Sky Centurion Diode-Pumped-Solid-State (DPSS) laser as the pump source and can operate at pulse repetition rates of up to 100 Hz. All optical components (including the pump laser, the OPO, and the optional UV modules) are mounted on a single optical frame. The laser head is extremely compact, with a footprint of only 9" x12", and is hermetically sealed to protect the optics. The control software, which is provided with the system, offers complete control of all the system functions, from laser operation to wavelength tuning and scanning. The system is portable and requires no maintenance.
