▪ A single-channel silicon-based thermopile detector
in a TO-5 package
▪ Four pin, 9.22mm TO-5 package
▪ Active area size is 0.61 × 0.61 mm
▪ Delivers a time constant of 18ms with Nitrogen
encapsulation gas
▪ Very low Temperature Coefficient of Responsivity
of -0.04%/°C
▪ Very short thermal shock response to ambient
temperature change
▪ Internal 5% NTC chip thermistor provides ambient
package temperature measurement
▪ Internal aperture precisely defines active area for
applications with FOV and/or spot size
requirements
