Features

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.

Thermoelectric Coolers
We offer three different single-stage thermoelectric coolers (TEC3-2.5, TEC3-6, and TEC1.4-6), all of which are ideal for medium to large heat-pumping applications. Our dual-stage TEC (Item # TECD2) provides a larger temperature differential between the hot and cold surfaces of the device; when the hot surface is 50 °C, it is capable of cooling the cold surface to -58 °C when in vacuum. The hot and cold surfaces of the dual-stage TEC are metalized copper for soldering in order to ease integration into the system.

All of our TECs work well with our TED4015 225 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers, which are compatible with 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.

Resistive Heaters
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.

Thermistors and Temperature Transducers
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; the TH10K can also be used with the MTD415T TEC controller in an SMT package. 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.

Should I try to widen the hole of HT19R by a few mms? Will this destroy the heater?

Are your TECs capable of both heating up and cooling down?

Thank you for contacting Thorlabs. Our TEC's are capable of both heating and cooling. The primary purpose of these TEC's is to cool but can be used to heat a device if the hot surface is in contact. For general heating purposes we recommend using our resistive heaters, thermistors and temperature transducers. I will reach out to you directly.

I don't see a maximum temperature spec on HT10K or TLK-H. Can you provide this information?

Response from Mike at Thorlabs: Thank you for your feedback. The temperature range for the HT10K and TLK-H is -32 to 100 °C (-26 to 212 °F). Based on your feedback this specification has been added to the web presentation for these parts.

What is the maximum operational temperature for the HT19R heater element? The heater element HT19R ships with a note saying the maximum is 180 C, while the data sheet online says 400 C.

Response from Sean at Thorlabs: Thank you for your pointing out this inconsistency. 400 °C is the correct maximum temperature specification. It appears that the item shipped with an older, incorrect version of the spec sheet; we are working with the production team to get the items in inventory corrected now.

How long are the leads on the HT10K? Or can you just solder on your own?

Response from Tim at Thorlabs: Thank you for your feedback. We will add the cable as a standalone item shortly (with HIROSE connectors for mating with TC200). For immediate assistance with a compatible cable, please contact us at techsupport@thorlabs.com.

Would be great if Thorlabs also sold connecting cable (connector one end and alligator or other quick clips on other end) to go between Thermistor, heating elements and one of the standard temperature controllers.

Performance values of the Single-Stage Thermoelectric Coolers (TECs) are given above 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 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.

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. For OEM, custom, or embedded systems, our OEM Temperature Controllers are available in SMT or THT Packages.

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.

  • 1" x 3" (25.4 mm x 76.2 mm) Heating Area
  • Adhesive Backing for Easy Installation
  • 10 W/in2 (0.016 W/mm2) Heating Capacity

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.
