(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.
