ELECTRO OPTICAL COMPONENTS, Inc.

InfraTec is a leader in the manufacture of high quality
pyroelectric sensors / detectors that are distributed in
North America exclusively by ELECTRO OPTICAL COMPONENTS, Inc.

Pyroelectric Sensors / Detectors

Sensors that measure radiation by means of the change of temperature of an absorbing material are classified as thermal detectors. Thermal detectors respond to any wavelength radiation that is absorbed and can be made to respond over a wide range of wavelengths.

One of the most common thermal sensors used in the infrared (IR) applications is the pyroelectric detector. Pyroelectric sensors made from lithium tantalate (LiTaO3) generate electric charges with small temperature changes, and are stable, uniform and durable. InfraTec produces a line of cost effective, high performance pyroelectric infrared sensors for a variety of commercial, industrial and military applications.

Low microphonic, high gain pyroelectric detectors

InfraTec offers the widest selection of pyroelectric detector options so you can select the optimum sensor for your application needs.
