The high-performance, solid-state cooling devices are specifically designed to control the temperature of heat-sensitive optoelectronic components used in laser diodes, optical transceivers, LiDAR, CMOS, and Infrared Range (IR) sensor applications.

Optoelectronic devices, such as laser diode packages, can reach operating temperatures as high as +85°C in an outdoor or air-restricted environment. Whether used for fiber optics in telecommunications, industrial processing, or autonomous systems, temperature stabilization is key to maintaining the laser diodes’ peak performance and ensuring long-life operation. Thermoelectric coolers utilize the Peltier effect to keep sensitive optical components below their maximum operating temperature. By reversing the polarity, thermoelectric coolers have the ability to heat or cool, which allows for a temperature control accuracy of up to ±0.01°C under steady-state conditions.

In footprints as small as 3 X 4 mm, the OptoTEC OTX/HTX Series offers high heat pumping capacity and improved temperature stability for optoelectronic applications with tight geometric space constraints. Offering up to 10 Watts of cooling power, the OptoTEC OTX/HTX series maintains a temperature differential ΔTmax (Qc = 0) of up to 82°C with a hot side temperature at 50°C. The product series has passed the Telcordia GR-468 CORE qualification to withstand harsh mechanical and environmental test standards and manufacturing process controls have been enhanced to ensure high repeatability and long-life operation.

The OptoTEC series is available in two versions. The OTX thermoelectric cooler is designed for operating temperatures up to 120°C while the HTX thermoelectric cooler uses a higher temperature construction to operate in temperatures up to 150°C. Custom configurations are available to accommodate metallization, pre-tinning, ceramic patterns, and solder posts.

The OptoTEC OTX/HTX Series is available from several authorized distributors. For more information or to buy now, visit our website.
