The 400 series is a modular system of signal processing electronics which provides a computer interface via the 417 for all of the optical detectors used in light measurement systems.
All the modules are housed in the 417 bin which includes the necessary stabilised power supplies, output display facilities and an integrated USB computer interface.
This range of 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.
