The TPS 334 L10.6 detector extends the features of the TPS 334 through an integrated micromachined silicon lens optics. In TO 5 type housing it employs a chip of 0.7 x 0.7 mm2 absorber size with a 30 kV thermistor as temperature reference and a lens with 10.6 mm focal length. An inlay in the housing suppresses reflections at the cap. The lens is not coated, but if a restricted wavelength region is desired (e.g. 8..14 mm), it is possible to equip the inlay with an additional filter (e.g. G9). The sensor shows a flat sensitivity characteristics over the wavelength. Parameters
