Multi-Stage Thermoelectric Peltier Modules
The Multi-Stage Thermoelectric Peltier Modules, also known as multi-stage thermoelectric elements or cascade modules, can built up high deltaT between the hot and cold side of the component. These Peltier elements are suitable for applications with very low target temperature where a low to medium cooling capacity is needed.
Typical applications are for example:
- IR detectors
- CCD array
- Electro-Optics
- measurement setups for very low temperatures
- Testing of Materials Test
These items are available in various cascade designs with different numbers of stages. Generally speaking, the more stages a module has the greater the achievable deltaT but the lower the possible thermal pumping capacity.
Uwe electronic as specialist for thermoelectric modules has a vast experience in the application of multi-stage Peltier modules.
- 2-stage TEMs

Type 2 (T2) TEMs feature a "porch" for more accurate heat distribution.
This makes the L2 dimensions slightly longer than the L1 dimension.
