Thorlabs offers a wide range of thermal management accessories, including thermoelectric coolers, resistive heaters, thermistors, and temperature transducers. Thermoelectric coolers are ideal for total and precise temperature regulation. These devices can both cool and heat, allowing for quick response to thermal drift or shock. For applications that require only heating or steady-state regulation slightly above room temperature, resistive heaters are a reliable and easily regulated heat source. Regardless of application, temperature monitoring is essential for any temperature regulation system. Thorlabs' thermistors and thermocouples provide precise and accurate temperature measurements.
We offer three different thermoelectric coolers (TEC3-2.5, TEC3-6, and TEC1.4-6), all of which are ideal for medium to large heat-pumping applications. These work well with both our TED200C 12 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers, which are compatible with the PRO800 Chassis. When using a TEC for thermal regulation, care should be taken to electrically isolate both sides of the TEC.
Thorlabs offers three types of resistive heaters: foil, cartridge, and metal ceramic. The HT10K and TLK-H are resistive foil heaters with a pressure-sensitive adhesive backing and a 10 kΩ NTC thermistor integrated directly onto the heater. The HT15W is a miniature 15 W cartridge heater, which can be used for many applications requiring small areas to be heated. Our metal ceramic heaters come in either round (HT19R) or square (HT24S and HT24S2) geometries and provide fast thermal response. These small, but high powered, heaters are ideal for thermal regulation of optical components. All of the heaters sold here are compatible with Thorlabs' TC200 temperature controller.
We also offer three models of thermistors and temperature transducers. The TH10K is a 10 kΩ thermistor with 1°C accuracy that is meant to be used in common TEC applications. The TH100PT is a 100 Ω platinum Resistance Temperature Detector (RTD) with a positive linear temperature response. These thermistors are compatible with the TC200 temperature controller. Finally, the AD590 is an integrated circuit (IC) temperature transducer with an output current that is proportional to absolute temperature. All our thermistors and AD590 temperature transducers are compatible with the TED200C 12 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers. For high temperature applications, constantan or manganese wires may be used.
