ILT Light Detectors


Please note: SEL, SCL, SPL, SSL, and XRL optical detectors are for use with the ILT1400 Radiometer / Photometer series.

SED, SCD, SPD, SSD, and XRD type optical detectors are for use with the ILT1700 Research Radiometer.

Example Detector Configuration: An optical detector for making photopic measurements with an ILT1700 is specified as "SED033/Y/W" and is found on photometry measurement applications page.

ILT's nomenclature for identifying optical detector assemblies is shown below. For many applications the detector/filter/input optic configuration best suited for the measurement is specified in the light measurement application section.

"SED" specifies detector housing style and meter connection (again SEL, SCL, SPL, SSL, and XRL detectors are for use with the ILT1400 Radiometer / Photometer series; SED, SCD, SPD, SPM, SSD, and XRD type detectors are for use with the ILT1700 Research Radiometer). In the above example, a SED type is indicated meaning it is for use with the ILT1700 Research Radiometer.

ILT Light Detectors
 

"O33" specifies the type of sensor used. In the above example, the 33mm² silicon photodiode is indicated.

"/Y" specifies filter(s) used. In the example above, the Y refers to our photopic filter.

"/W" specifies the input optic used for illuminating the detector. In our example, the W indicates our wide-eye diffuser.

The /U following the part numbers below indicates an UNCALIBRATED sensor.

Application-specific optical detector assemblies (shown on the Light Measurement Application Pages) such as the SED033/Y/W include a calibration therefore the /U is not noted in the part number.

The SED and SEL 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 only the SED and SEL type housings allow for underwater modification. All underwater modified SED or SEL optical detectors require the W wide-eye diffuser in addition to any other filters.

The SCL and SCD type optical detectors are in a 43 x 19 x 15 mm wand style housing.

The SSL and SSD type optical detectors are ultra-low profile detectors on a 29 x 38 x 2 mm thick board.

The XRL and XRD type optical detectors are in a 12.5 x 42 mm dia. housing, and the SPL and SPD type detectors are in a 121 x 19 mm dia. pen style housing. These four versions do not have removable, swappable filters and cannot be made waterproof.

NS405 filter with teflon diffuser can be mounted in XRL housing to create a low profile sensor to measure 400-405 nm. (should not be used with most WBS filters do to secondary response in the IR) Filters and optics are epoxied in place and cannot be removed.
Custom orders are non-refundable. Please contact a sales engineer for a price quote, or assistance with filter selection.
