S60M TO-5 Thermopile Detector

S60M TO-5 Thermopile Detector

A single-channel silicon-based thermopile with very high output for its small 0.6mm x 0.6mm active area in a TO-5 package. Delivers a very low Temperature Coefficient of Responsivity of -0.04%/°C.

High output, small active area, fast time constant that has a higher cost.

Excellent for non-contact temperature and gas analysis.


  1. See Standard Windows and Filters (PDF) for list of optical filter options
  2. Internal aperture precisely defines active area for applications with FOV and/or spot size requirements. See Aperture Options (PDF) for available sizes.
  3. See Thermopile Configuration Table for more options.

For more detailed information see the datasheet S60M TO-5 (PDF).

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