(OSI Optoelectronics: Hawthorne, CA)—OSI Optoelectronics announces its dual indium gallium arsenide (InGaAs) sandwich detector series for physical and chemical sciences, astronomy, aerospace, and measurement analysis applications.

Enclosed in compact, hermetically-sealed packages, the two-color sandwich detectors feature low noise, fast response times, and high responsivity over a wide wavelength range. Available with or without an integrated thermoelectric cooler (TEC), these detectors are highly resilient in volatile environmental conditions and maintain precise measurements across a broad temperature range.

Typical applications for two-color detectors include spectrophotometers, flame temperature sensing, infrared thermometers for heat treating, induction heating, and metal parts processing.

Temperature analysis applications measuring radiant energy distributions against black-body radiation curves benefit from simultaneous sampling across two chips. The dual-color photodiodes are unaffected by contaminants in the field of view (FOV) or moving targets, making them ideal for applications such as engine temperature monitoring and infrared target detection.

OSI Optoelectronics also offers the following two-color photodetector configurations: silicon-silicon, silicon-InGaAs, and the silicon-InGaAs with a two-stage TEC.
