The OTP-336 sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of diameter 700 μm.
The size of the housing is a TO5-package with a window opening. The window is equipped with an IR-transmissible filter and a lens.
The thermopile sensor provides nearly Johnson-noise-limited performance, which can be calculated by its ohmic series resistance.
A thermistor with a lead connected to ground is also provided inside the TO package for ambient temperature reference.
