OL 730D Programmable DSP Radiometer

Product Description:

Utilizing state-of-the-art digital signal processing (DSP) techniques, the OL 730D delivers outstanding performance in all applications requiring lock-in amplification techniques. It features several modes of operation depending on the type of amplification desired, is completely microprocessor controlled and can be programmed to read directly in any radiometric or photometric optical quantity. Though designed primarily for use with optical radiation detectors, the OL 730D is a highly versatile instrument that can replace many types of amplifiers in one compact, easy-to-use unit.
