Great for cooling detectors…

TM2 30-15-2.8 is a two-stage cascade style thermoelectric cooler with a ∆Tmax of 95 °C (∆Tmax 105 °C with T_h of 50 °C). That's up to 25 °C more ∆T than is possible with a single-stage module. A larger ∆Tmax is desirable for cooling some sensors, detectors and devices that work best at temperatures lower than is possible with a single stage module.

The 15x15mm cold-side will accommodate many of these devices, and others, while the 30x30mm hot-side provides a substantial surface area for heat-sinking. Typically powered by 12 or 15 volt DC power sources.

In electro-optic and photonic applications, TM2 30-15-2.8 is commonly used to maintain a cold, and constant, temperature in order to stabilize the wavelength detector or sensor.
