(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 Recommended Operating
Conditions. 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.
