Digital Light Processors make use of millions of micromirrors to produce vibrant, high-resolution images on a screen.

The tiny micromirrors are placed on a semiconductor chip, known as a Digital Micromirror Device (DMD). This technology can be found in several industries ranging from Head-up displays and Smart headlights in the automotive market, Smartphones and other display and projection applications to advanced light control in 3D printing.

Due to the extreme temperature environment these devices can be exposed to, engineers encounter a variety of thermal challenges when integrating digital light processing technology, including thermal noise, SWaP (size, weight, and power) constraints, lack of airflow, and outgassing. Digital light processors need to be kept below their maximum operating temperature to avoid image quality degradation and ensure maximum system uptime.
