Thermal resistance, active area to test point 1 (TP1)(1)

(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 DMD 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. Minimizing the light energy falling outside
the window's clear aperture is a design requirement of the optical system because
any additional thermal load in this area can significantly degrade the reliability
of the device.
