It uses a scalar irradiance collector to obtain a uniform directional response over 3.6-pi steradians. A stainless steel encased optical light pipe guides flux from the collector to a filtered silicon photodetector, resultng in a flat quantum response over the PAR spectral region (400-700 nm). The sensor produces a logarithmically compressedanalog voltage output and BH-4-MP connector Operates in waters depths up to 2000 m."@en . "QSP-2350 underwater PAR" . "QSP-2350 underwater PAR"@en .
