730C Optronic Laboratories Programmable Radiometer / Photometer

The Optronic Laboratories 730C Programmable Radiometer / Photometer sets the standard when it comes to superior performance, accuracy, sensitivity, and versatility. The OL 730C is a completely microprocessor controlled, high sensitivity radiometer/photometer which can be programmed to read directly in any user specified radiometric or photometric optical quantity. The Radiometer/Photometer features high sensitivity, auto-ranging, auto-zeroing, highly accurate readout and range-to-range linearity, 4.5 digit plus exponent display, variable response time, RS-232 interface (IEEE-488 optional), multiple detector operation, and extremely large dynamic range. The basic OL 730C is furnished with an internal preamplifier and has a sensitivity of 1 X 10¹⁴ amperes. The optional detectors available for use with the OL 730C include silicon, photomultipliers, germanium, and InGaAs. In addition, an ultra high-sensitivity silicon detector with the amplifier built into the detector head is available that has a noise level of 10¹⁵ amperes when used with the OL 730C. This combination has a radiometric sensitivity of 2 X 10¹⁵ watts at 900 nm and a photometric sensitivity of 10¹¹ lumens.

The OL 730C can be programmed to read directly in any user specified radiometric or photometric optical unit. Multiple calibration factors for different detector/filter/input optic configurations can be stored in memory. Once the desired detector/filter/input optic configuration and associated calibration factor is selected, the OL 730C will measure and read directly in the designated optical units.
