All Weather Light Detector

Gigahertz-Optik's WPD series weatherproof detectors are designed for year round outdoor light measurement in solar and solar simulated optical radiation monitoring applications.

To withstand the most demanding environmental conditions the entire light sensor is shielded in a rugged metal housing with the front input optic enclosed and sealed under a precision-made quartz dome.

Photodiode, filtering and diffuser are temperature stabilized to +25° C (stable to +/- 1° C) by means of a Peltier cooler. The WPD detector operating temperature range is —20 to 50 deg C.

The WDP's PTC-0101 Peltier Temperature Controller electronics are contained in a separate compact bench-top or rack-mount housing with cable connection to the WPD detector.

Any Gigahertz-Optik light detector elements can be integrated into the WPD housing covering the ultraviolet, visible or near-infrared spectral regions. The WDP series detectors are normally used with a GO optometer or amplifier for direct measurement in any optical unit and datalogging.
