1SC Compensated Thermopile

1SC Compensated Thermopile

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 1SC (PDF).

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