OptoTEC™ MSX Micro Thermoelectric Coolers

Tark Thermal Solutions OptoTEC™ MSX Micro Thermoelectric Coolers (TECs) feature advanced automation and next-generation thermoelectric materials, boosting cooling capacity by 10%. These MSX coolers are available as standalone units or can be integrated into an optical package via a proprietary bonding technique that adheres TECs to the optical package with minimal solder voiding. OptoTEC MSX coolers from Tark Thermal Solutions are suitable for infrared (IR) detectors, charge-coupled devices (CCD), X-ray detectors, and complementary metal-oxide-semiconductor (CMOS) devices.
