Erythemal Light Detector: JEC0.3E Jan 3, 2008

Erythemas, abnormal redness of the skin, can be assessed using SiC detectors. To provide meaningful information it is important for the detector to respond closely to the erythemal CIE 87 curve.

IFW’s erythemal detectors have a long history of reliability and robust performance, in particular under high UV radiation conditions. No other detector on the market matches the erythemal curve as precisely as the JEC1I-DE device. High quality SiC chips and special, carefully selected filters are used for this detector.

Now available is the JEC0.3 E “light” detector in a fully hermetic TO39 metal housing, which is a relatively inexpensive device without an integral diffusion window. When normal incident light falls on the detector, the UV-B range and the transition from UV-B to UV-A are mapped precisely. The sensitivity gradient approximates to the erythemal CIE 87 curve, and is optimised for solar applications.
