Recommended Operating Conditions (continued)

Over operating free-air temperature range (unless otherwise noted). The functional performance of the device specified in this

data sheet is achieved when operating the device within the limits defined by this table. No level of performance is implied

when operating the device above or below these limits.

Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination reduces

device lifetime.

(10) The mirror temperatures cannot be measured directly and must be computed analytically from the temperature measured at test point 1

(TP1) shown in Figure 20 and the DMD package and mirror thermal resistances using the Micromirror Temperature Calculations.

(11) Long-term is defined as the usable life of the device.

(12) Per Figure 2, derate the maximum operational micromirror temperature based on the micromirror landed duty cycle that the DMD

experiences in the end application. See Micromirror Landed-On/Landed-Off Duty Cycle for a definition of micromirror landed duty cycle.

(13) Mirror temperatures beyond those specified as long-term are recommended for short-term conditions only (power-up). Short-term is

defined as cumulative time over the usable life of the device and is less than 500 hours.

(14) The locations of thermal test points TP2, TP3, TP4, and TP5 in Figure 20 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, add test points to those locations.

(15) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge as shown in

Figure 20. The window test points TP2, TP3, TP4, and TP5 shown in Figure 20 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 temperature, use that point.

(16) The average over time (including storage and operating) that the device is not in the ‘elevated dew point temperature range'.

(17) Limit exposure to dew point temperatures in the elevated range during storage and operation to less than a total cumulative time of

CTELR.

(18) See Figure 1 for allowable combinations of illumination power vs illumination power density. 160W total power is achievable only by full

array illumination. 500 W/cm2 is only achievable through partial array illumination. Some combinations of illumination power and power

density require cooling of the window with forced air as defined by Figure 1. Refer to the application note DLP® High Power Thermal

Design Guide: Focus on High Power NIR Laser Illumination for additional details.
