Mentor Graphics Corp. has introduced the T3Ster (“trister”) thermal transient tester for LEDs, board-level LED arrays and luminaires. Together with the company’s FloTHERM thermal simulation tool based on computational flow dynamics (CFD), lighting designers can model and improve heat transfer through the LED, printed circuit board (PCB) or luminaire system during design and … [Read more...]
Back Illumination Deep Depletion CCD Camera
Princeton Instruments’ new 1024BR CCD camera utilizes a back illuminated CCD with larger depletion region. This allows the camera to achieve much higher quantum efficiency in the NIR region. The camera is optimized to provide the best signal-to-noise (SNR) ration required for challenging NIR applications such as photoluminescence. Learn more from Princeton Instruments. … [Read more...]
Thermoelectrics that use Electricity to Provide Cooling Power
Phononic Devices is building thermoelectric modules that use electricity to provide cooling power. Such modules essentially replace the flow of refrigerants through vapor compression cooling systems with the flow of electrons through a chip. Solid-state cooling would eliminate a system's moving parts and its refrigerants, which are usually potent greenhouse gases. And with the … [Read more...]
New Material Provides Greater Thermoelectric Conversion Efficiency
Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy’s Ames Laboratory. A team of researchers at the Lab that is jointly funded by the DOE Office of Basic Energy Sciences, Division of Materials Sciences and Engineering and the Defense Advanced … [Read more...]
New Thermoelectric Module for Photonics Cooling
Nextreme Thermal Solutions recently introduced the OptoCooler HV37 module, the next product in its high-voltage (HV) line of thin-film thermoelectric coolers (TECs) designed to address photonics cooling applications with larger heat pumping requirements. At 85°C, the OptoCooler HV37 can pump 4.5 watts or 107W/cm2 of heat in footprint of only 6 mm2. The device is only 0.6mm … [Read more...]
