Laser Servo gets positive feedback from users

Elliot Scientific has had commendations from laser scientists around the UK after trials with the D2-125 laser servo from Vescent Photonics.

Designed for low-noise servo control of lasers and other experimental systems, the reconfigurable servo is equipped with a PI2D loop filter (with two-stage integral feedback) that provides tight locking to cavities and atomic/molecular transitions.

The D2-125 provides full control over the loop-filter parameters, enabling servo-loop optimisation for a wide variety of systems such as acousto and electro-optic actuators, voice coils, piezo actuators, and so on.

Auto relocking is available for the D2-125 Laser Servo as an option. Lock Guard™ detects when the servo loop filter has gone out of lock and automatically recaptures it.  Lock Guard™ control parameters are all user adjustable for maximum flexibility and optimal performance.

Key research areas for Vescent products are:

  • Magneto-Optical Traps (MOT) for laser-cooling of atoms
  • Coherent atom sources
  • Sensors for gravitometry and magnetometry
  • Focused ion beams
  • Ultrasensitive trace-isotope analysis
  • Quantum computing and cryptography

The “World’s Most Accurate” Capacitance Bridges are from Andeen-Hagerling

Andeen-Hagerling AH2700A Capacitance Bridge Test Instrument

Andeen-Hagerling manufacture the world’s most accurate capacitance bridges and standards, and their AH 2700 models offer unparalleled stability, resolution, linearity and accuracy in a multi-frequency capacitance/loss bridges.
Andeen-Hagerling AH2700A Capacitance Bridge Test Instrument
The numerous state-of-the-art features of the AH2700 make it an exceptionally user-friendly instrument, with unmatched precision that enables it to open up new applications in calibration, manufacturing and scientific research.

The AH2700 is the culmination of over 40 years of Andeen-Hagerling experience in bridge design and manufacture. The unique ratio transformer and the temperature-controlled, fused-silica capacitance standard make the instrument a true bridge for measuring highly accurate capacitance/loss figures which are independent of the exact test frequency (50 Hz – 20 kHz) and immune to mechanical shock.
