ILT Light Detectors


ILT detectors are designed to emit low levels of current in the pico-amp to milli-amp range which is then converted to calibrated optical units such as lux, W, W/cm2... when used with ILT light meters.Detector assemblies typically include a sensor, filter, optic and calibration.

Example of a calibrated detector assembly for lux: "SED033/Y/W" includes the “SED033” 33mm² silicon photodiode detector, the “Y” photopic correction filter with the “W” Diffuser and calibration.

(Note: “/U” indicates an uncalibrated sensor).

The SED and SPM type optical detector housings are made of black anodized aluminum, with female filter threads (1¼-24), a tripod mount (¼-20), and two end mounts (#8-32). Only these housings allow for filter selection/swapping and underwater modification. All underwater modified detectors (SUD) require the W wide-eye diffuser in addition to any other filters and come special order in10, 50 or 100 foot lengths.
