Thin Film Based Thermopile Detector: 2 or 1 Channels
DR46
A two-channel or a one-channel compensated thin-film thermopile in a TO-8 package. Each active area is 4mm x 0.6mm. Offers high output with excellent signal-to-noise ratio. An internal aperture minimizes channel-to-channel crosstalk increasing sensitivity.

1SC Compensated
A thin film-based single channel thermopile detector that offers thermal compensation to minimize effects of sudden ambient temperature change during the initial five seconds of change. The 1SC Compensated comes in a TO-5 package with a medium sized 1.0 x 1.0mm active area. Compensation is achieved through the integration of two additional half-sized thermopile elements. Internal aperture is standard and precisely defines active area for applications with FOV and/or spot size requirements.

ST60 High Temperature
A single-channel silicon-based thermopile that will withstand operating temperatures of 225C, with a small active area of 0.61mm x 0.61mm in a TO-5 package. The reduced height package functions as an internal aperture. Two thermistor options provide ambient package temperature measurement. Currently only available with 8-14um silicon window. Time constant of 18ms with Nitrogen encapsulation gas delivers a very low Temperature Coefficient of Responsivity of -0.4%C. This detector has a very short thermal shock response to ambient temperature change.
