Nothing Senses Better Than a Dexter Detector

1SC Compensated

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

See Standard Windows and Filters (PDF) for list of optical filter options.
See Thermopile Configuration Table for more options.
