The ETX14-12-F1-6262-TA-RT-W6 high temperature, high-performance thermoelectric cooler uses Laird's enhanced thermoelectric module construction preventing performance degrading copper diffusion, which is common in standard grade thermoelectric coolers operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 138 Watts when ΔT = 0 and a maximum ΔT of 83.2 °C at Qc = 0.

CCTV and IP security cameras are being installed in public areas to prevent crime and increase safety while thermal cameras are used for boarder and facility security at night.
Due to sun exposure and heat generated by surrounding components, the operating temperature of security cameras can be as high as 90°C. Lack of airflow, outgassing and thermal noise are other thermal challenges that needs to be taken into consideration when designing cameras for outdoor environments.
The use of outdoor cameras has seen a massive influx with the rise in security monitoring by government and private security agencies. Security cameras are installed with an objective to reduce crime or to improve public safety. CCTV and IP security cameras are installed on every corner in cities, outside hotels and retail stores, all around entertainment venues, stadiums and other commercial and industrial properties. Thermal cameras (infrared sensing) are now often used to improve facility and boarder security at night.
The lasers in Lidar systems, particularly those used in outdoor autonomous applications, require active cooling to achieve maximum resolution in high-temperature environments. As temperatures increase, the wavelength of the laser changes, resulting in increased range error. Maintaining operational temperatures within a Lidar system’s temperature limits ensures peak performance.
High-performance thermoelectric coolers offer a flexible active cooling option for spot cooling of Lidar sensors.
For all these packages Laird Thermal Systems manufactures several different series of thermoelectric coolers:
The OptoTEC™ OTX/HTX Series miniature thermoelectric cooler. Designed for lower current and lower heat-pumping applications, the OptoTEC™ OTX/HTX Series Series keeps the laser diode operating temperature stable at around 25+/-0.5°C, achieving a temperature accuracy of ±0.01°C.
Additive manufacturing, better known as 3D printing, is an emerging application that is finding an expanding purpose in the manufacturing process. Once primarily used for quickly making prototype parts, 3D printing is now also used to digitize workflow and manufacture production quality final products. There are many different types of 3D printing methods used to physically create a desired object.
When 3D printing evolved in the 1990s it was only considered to be suitable for prototyping parts. With improved materials, precision and repeatability, the technology is now frequently used in manufacturing of final products and digitization of workflows. 3D printing machines utilize lasers to stack (print) layer after layer of melted plastic resin or metal to create a solid three-dimensional part. This laser, or electron beam generates a tremendous amount of heat that needs to be dissipated away from sensitive electronics to assure high quality 3D objects and long-life operation.
