Thorlabs offers a variety of heaters for use with our vapor reference cells and empty glass cells: the GCH25-75 heater assembly features 15 W max heating capacity and is also compatible with our 30 mm cage system, the GCH25R cap heater is designed to be mounted on the end of Ø25 mm glass cells, and our flexible resistive foil heaters feature adhesive backing for attachment to glass cells or lens tubes. Each of these heaters is compatible with our TC200 Temperature Controller.

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.
The GCH25-75 glass cell heater uses two built-in heating elements to raise the temperature of a vapor cell to as much as 50 °C (when room temperature is 25 °C; limited by the heater unit). The temperature is monitored using a Minco Thin Film Element sensor. Adapter rings for Ø9 mm and Ø19 mm cells are included. Without the use of adapters, the heater mounts Ø25 mm cells. This allows the heater to be used with our standard reference cells. The heater incorporates Ø6 mm cage rods and is compatible with our 30 mm cage system.
Thorlabs' TC200 Temperature Controller (sold separately) is the ideal controller to maintain the heater temperature. Each heater ships with two Hirose cables to directly connect to the main and auxiliary output of the temperature controller. The auxiliary output allows for full operation of the reference cell heater using only one controller.
The GCH25R cap heater is designed for use with Ø25 mm glass cells. It incorporates our HT10KR metal ceramic heater, which is a 10 W ring-shaped heater with a 10 kΩ thermistor. The aluminum housing features a double bore with a nylon-tipped setscrew to hold it in place at the end of the cell. Two cap heaters (sold separately) may be used on opposite ends of the glass cell.
This heater features bare wire leads for use with a user-provided connector. The red leads of the heater are connected to the resistive heating element while the white leads are connected to the thermistor. A TC200CAB10 Hirose cable can be used to connect a GCH25R heater to the TC200 Temperature Controller (each sold separately). For this purpose, the Hirose cable must be cut and wires exposed.
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 Kapton (polyimide) 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.
