THERMOPILE INFRARED SENSOR
Date : Oct. 10, 2000
▓
Features The thermopile sensor consists of a series of 44 thermoelements, forming a sensitive area of 0.5*0.5 mm2. The sensor is hermetically sealed into a TO-18 metal housing, with optical filter. This standard filter allows measurements to be made in the spectral range above 5µm wavelength. The thermosensor exhibits an almost white noise, comparable to an ohmic resistance. It has a constant signal versus frequency up to its frequency limit, and is directly proportional to incident radiation.
