The following range of units allow the user to configure high quality dc and lock-in amplifiers with current and/or 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 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.

The 200 series is a modular system of signal processing electronics which aims to provide a GP-IB (IEEE488) 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.

The ORM400 is a stand-alone Optical Radiation Meter, equipped with a USB 2.0 interface, powerful calibration features and data display functions. It is ideally suited to display the measurements from current generating detectors, like the DH400 range.
The ORM400 includes a library of standard spectral light sources to which customers may add. This enables the greatest accuracy and flexibility when measuring light sources with a filter based instrument.
