UV-3718

The detector head UV-3718 is designed for narrow band UV-C 254 nm radiation sources with distinct 254 nm Peak Emission spectrum. Optical filters are used to shape the bare photodiode response to the desired spectral bandpass. 

Pre-aged Components 

All optical and optoelectronic components of the UV-3718 detector pre-aged by UV-C Radiation for extended long time stability.

Cosine Field-of-View

A cosine F.O.V. characteristic of the detectors spatial responsivity is effected by the diffusor window of UV-3718 detector. The diffursor window is made by UV stable RADIN material. . 

Designed for Wide Dynamic

The UV-3718 detectors is designed for the highest possible irradiance sensitivity for low irradiance level applications. However the wide range linearity of the photodiodes coupled with the Gigahertz-Optik optometers’s wide dynamic signal range amplifiers enable the UV-3718 detector to be used in applications with high irradiances as well. The upper range is limited only by the detector maximum operating current and its specified operation temperature. 

UV-C stable Housing and cable

The UV-3718 irradiance detector is built in a compact 37mm diameter black anodized aluminum housing. A side M6 tapped mounting hole allows the detector be fixed in place 

Traceable Calibrations 

Calibration of irradiance in W/m² and/or W/cm² as well as the detector's relative spectral responsivity is performed at Gigahertz-Optik’s Calibration Laboratory. Beside the regular calibration with spectral broadband reference lamps alternative calibrations with monochromatic or custom type reference lamps can be supplied as an option. The calibration and its traceability are confirmed in the calibration certificate supplied with each detector.
