Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination will reduce device lifetime.
The locations of thermal test points TP2, TP3, TP4, and TP5 shown in Figure 7-1 are intended to measure the highest window edge temperature. For most applications, the locations shown are representative of the highest window edge temperature. If a particular application causes additional points on the window edge to be at a higher temperature, test points should be added to those locations.
Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge as shown in
 Figure 7-1. The window test points TP2, TP3, TP4, and TP5 shown in Figure 7-1 are intended to result in the worst case delta
temperature. If a particular application causes another point on the window edge to result in a larger delta in temperature, that point
should be used.
The average over time (including storage and operating) that the device is not in the ‘elevated dew point temperature range'.
Exposure to dew point temperatures in the elevated range during storage and operation should be limited to less than a total
cumulative time of CTELR.
The maximum marginal ray angle of the incoming illumination light at any point in the micromirror array, including Pond of Micromirrors (POM), should not exceed 55 degrees from the normal to the device array plane. The device window aperture has not necessarily been designed to allow incoming light at higher maximum angles to pass to the micromirrors, and the device performance has not been tested nor qualified at angles exceeding this. Illumination light exceeding this angle outside the micromirror array (including POM) will contribute to thermal limitations described in this document, and may negatively affect lifetime.
The maximum allowable optical power incident on the DMD is limited by the maximum optical power density for each wavelength range specified and the micromirror array temperature (TARRAY).
