Thermal Resistance, active
area to test point 1 (TP1)(1)(2)

°C/W
(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 Section 5.4. 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's clear aperture since any additional thermal load in this area can
significantly degrade the reliability of the device.
(2) The thermal resistance
values provided here assume a non-uniform illumination profile. Refer to
Micromirror Array Temperature Calculation for details.
