The 200 series is a modular system of signal prcessing electronics which aims to provide a computer interface for all of the optical detectors used in light measurement systems.

All the modules are housed in the 217 bin which includes the necessary stabilised power supplies and output display facilities.

This range of GP-IB programmable units allow the user to configure high quality dc and lock-in amplifiers with current voltage inputs to suit all optical detectors.

An optical chopper, high voltage supply and programmable relay/utility module can also be included to provide an 'all-in-one-box' optical detection system which is equally at home in one of our spectroradiometers or as a general purpose laboratory instrument.

The 217 and 217T provide power, housing and shielding for all of the 200 series modules.

The 217T will accommodate 5 single-width units and the 217 will accommodate 8 single width units, or any combination adding up to the width of eight single units.
