S60M* TO-5

Silicon Based Thermopile Detector

Features: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 fast 12ms time constant in Argon encapsulation gas and even faster with Neon gas at 9ms.Delivers a very low Temperature Coefficient of Responsivity of -0.04%/°C.

Applications:Excellent for non-contact temperature and gas analysis.

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

Options:

  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.

Datasheet: For more detailed information see the datasheet (PDF).
