July 26, 2021 – Laird Thermal Systems has launched the enhanced OptoTEC™ OTX/HTX Series of miniature thermoelectric coolers designed for high-temperature environments found in telecom, industrial, autonomous and photonics applications. Featuring next generation thermoelectric materials, the OptoTEC OTX/HTX Series offers a 10% boost in cooling capacity, greater temperature differential and higher efficiency than standard thermoelectric coolers. 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 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 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.
"Temperature stabilization of optoelectronic components in high
temperature environments is no easy task," said Andrew Dereka,
Thermoelectrics Product Director at Laird Thermal Systems. "Our OptoTEC
OTX/HTX series uses new thermoelectric materials and enhanced process
controls to meet the demands of the optoelectronics industry by offering
higher cooling performance in a miniature form factor"
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.
