(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.
