OptoTEC™ OTX/HTX Series

High-performance thermoelectric cooler for temperature stabilization of optoelectronics

The OptoTEC Series is a high-performance, miniature thermoelectric cooler that utilizes next-generation thermoelectric materials to boost cooling performance over standard product offerings. Process controls have been enhanced to assure repeatability and long-life operation in temperature stabilization applications for optoelectronics used within telecom and industrial laser markets. This product line has passed Telcordia GR-468 CORE qualification to withstand harsh mechanical and environmental test standards.

The OptoTEC series is available in two formats. The OptoTEC OTX thermoelectric cooler has a maximum operating temperature of 120°C. The OptoTEC HTX thermoelectric cooler is designed to operate in extreme temperatures of up to 150°C. Custom configurations are available to accommodate metallization, pre-tinning, ceramic patterns and solder posts.
