LASER COMPONENTS Pyro Group (Olching, Germany) produces pyroelectric DLaTGS detectors - three series are available: One for users who would like to combine their detectors with their own electronics (LCDT-5000 series); the LCTDT-5100 series is designed for low-fre¬quency applications in the range of 10-100 Hz, and the LCDT-5500 type with a low-noise JFET is designed for FTIR applications. All detectors possess thinned-out ele¬ments and optionally feature an absorbing black coating with a low thermal mass that offers a wide spectral response at a simultaneously high speed. All pyrodetectors are available with different diameters of their active surfaces and rectangular and square shapes as well. Standard housings include TO-5, TO-66, and TO-37.
