This heatsink is a high-end TEC and FAN based cooler. It is used to enhance performance of narrow spectrum laser in spectroscopy and holography applications, which needs extreme central wavelength stability or extended operational temperature range.

In combination with this TEC cooler, Matchbox lasers will gain numerous of stability and operational temperature range enhancements for demanding scientific and industrial setups. The cooler electronics board provides power to the laser mounted on top. It also communicates with the laser to read its body temperature and then stabilizes the laser body temperature most accurately.
