1SC Compensated Thermopile

Thin Film Based Thermopile Detector

Features:
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.
Applications:
Excellent for non-contact temperature measurement.
Benefit:
Thermal compensation with increase in noise and a time constant of 48ms in Argon encapsulation gas.
Options:
  1. See Standard Windows and Filters (PDF) for list of optical filter options.
  2. See Thermopile Configuration Table for more options.
Datasheet:
For more detailed information see the datasheet

Specifications apply at 23°C with KBr Window and Argon encapsulating gas.
