Thorlabs offers a wide range of thermal management accessories, including thermoelectric coolers, resistive heaters, thermistors, and temperature transducers. Thermoelectric coolers can both cool and heat, allowing for quick response to thermal drift or shock. These devices are ideal for total and precise temperature regulation. 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. Thermoelectric Coolers All of our TECs work well with our TED4015 225 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers, which are designed for the PRO800 Chassis. These TECs can also be driven by our OEM Temperature Controllers in SMT or THT Packages. When using a TEC for thermal regulation, care should be taken to electrically isolate the sides and leads of the TEC. *Please be aware that the max current of the TC200 is 0.75 A. This may inhibit the max power of the heater being used.
![]() Performance specifications are given in the table below as a function of TH, the temperature of the hot surface of the TEC. Imax is the maximum allowed current across the TEC element and Vmax is the maximum allowed voltage difference. These values should not be exceeded. Qmax is the maximum heat load that the TEC can handle; ΔTmax is the maximum temperature difference between the hot and cold surfaces of the TEC in a dry nitrogen environment. When choosing a TEC, it is important to know the heat load, or cooling capacity, of the system (how much heat must be transferred away from the device) and to match that load with a capable TEC. The TEC should be rated for a maximum heat load above that which is emitted by the system, and a sufficiently large heat sink must be attached to the hot surface. Proper thermal contact is necessary for optimal heat transfer. Ensuring that the TEC is of the proper size for the system is important as well as using thermal tape or grease to help facilitate heat transfer. It is important to note that the heat transfer efficiency is affected by the ambient environment; care must be taken to avoid condensation on the cold side. Large changes in background temperature or significant humidity can hamper heat flow. These factors should be taken into account when choosing an appropriate TEC. All the TECs available here, with the exception of the TEC3-2.5, TEC3-6, and TEC1.4-6, are silicone sealed to protect the core from moisture and condensation. We offer several kinds of temperature controllers for our TECs. The TED4015 225 W TEC Controller is a benchtop laser diode temperature controller with excellent temperature stability. Our rack-mountable temperature controllers are also capable of excellent temperature stabilization and additionally are compatible with the PRO800 Chassis. For OEM, custom, or embedded systems, we offer OEM Temperature Controllers in SMT or THT Packages as well as on a PCB with mounting standoffs. ![]() ![]() Click for Details Dual-Stage TEC Dimensional Drawing
Our Dual-Stage Thermoelectric Cooler (TEC) is ideal for situations where additional cooling is required. The TECD2 provides a temperature difference between the hot and cold surfaces of up to 108 °C when the hot surface is at 50 °C. The hot and cold surfaces are metalized copper to allow for soldering. This TEC is designed to operate in vacuum levels of 10-6 Torr with proper cleaning and bake out. The performance values for our Dual-Stage TEC is given as a function of TH, the temperature of the hot surface of the TEC. Imax is the maximum allowed current across the TEC element and Vmax is the maximum allowed voltage difference. These values should not be exceeded. Qmax is the maximum heat load that the TEC can handle; ΔTmax is the maximum temperature difference between the hot and cold surfaces of the TEC in vacuum. When choosing a TEC, it is important to know the heat load of the system (how much heat must be transferred away from the device) and to match that load with a capable TEC. The TEC should be rated for a maximum heat load above that which is emitted by the system, and a sufficiently large heat sink must be attached to the hot surface.

We offer three kinds of temperature controllers for our TECs. The TED4015 225 W TEC Controller is a benchtop laser diode temperature controller with excellent temperature stability. Our rack-mountable temperature controllers are also capable of excellent temperature stabilization and additionally are compatible with the PRO800 Chassis.

These 1" x 3" (25.4 mm x 76.2 mm) foil heating elements are useful for many lab applications. They have an integrated thermistor for closed-loop temperature control and an acrylic pressure-sensitive adhesive backing for easy installation. Both models use the same heating element. The HT10K features bare wire leads for use with a user-provided connector. Alternatively, the TLK-H connects to the TC200 Temperature Controller* using our TC200CAB10 6-Pin Hirose Cable (sold separately), eliminating the need to wire the foil heater into the controller. Both foil heaters are flexible for use in applications such as heating lens tubes, as shown in the photo to the right. In this application, the lens tube can be isolated from the rest of the system using a Thermally Insulating Adapter. *Please be aware that the max current of the TC200 is 0.75 A. This may inhibit the max power of the HT10K. ![]()
The HT15W is a 15 W cartridge-shaped resistive heater. It is compatible with our TC200 Temperature Controller. Please be aware that the max current of the TC200 is 0.75 A. This may inhibit the max power of the HT15W. ![]()

These Metal Ceramic Ring Heaters contain 10 kΩ thermistors. The HT10KR Ø25 mm heater is also incorporated in our GCH25R Cap Heater for Ø25 mm glass cells. Both heaters can be used with the TC200 Temperature Controller. Please note that the max current of the TC200 is 0.75 A; this may inhibit the max power of the heaters. ![]()
