(1) The DMD is designed to conduct absorbed and dissipated heat
to the back of the package. The cooling system must be capable of maintaining
the package within the temperature range specified in the Section 6.4. The total
heat load on the DMD is largely driven by the incident light absorbed by the
active area although other contributions include light energy absorbed by the
window aperture and electrical power dissipation of the array. Optical systems
should be designed to minimize the light energy falling outside the window clear
aperture since any additional thermal load in this area can significantly
degrade the reliability of the device.
