β Micromirror Tilt Angle Variation, device to device (see (1) and Figure 9) –1 1 °

(1) Mirror Tilt: Limits on variability of mirror tilt are critical in the design of the accompanying optical system. Variations in tilt angle within a device may result in apparent non-uniformities, such as line pairing and image mottling, across the projected image especially at higher system F/#. Variations in the average tilt angle between devices may result in colorimetry, brightness, and system contrast variations.
(2) DMD efficiency is measured photopically under the following conditions: 24° illumination angle, F/2.4 illumination and collection apertures, uniform source spectrum (halogen), uniform pupil illumination, the optical system is telecentric at the DMD, and the efficiency numbers are measured with 100% electronic mirror duty cycle and do not include system optical efficiency or overfill loss. Note that this number is measured under conditions described above and deviations from these specified conditions could result in a different efficiency value in a different optical sytem. The factors that can incluence the DMD efficiency related to system application include: light source spectral distribution and diffraction efficiency at those wavelengths (especially with discrete light sources such as LEDs or lasers), and illumination and collection apertures (F/#) and diffraction efficiency. The interaction of these system factors as well as the DMD efficiency factors that are not system dependent are described in detail in the DMD Optical Efficiency Application Note, which can be accessed by contacting TI Applications Engineering.
(3) Optical parameters are characterized at 25°C.
(4) A non-operational micromirror is defined as a micromirror that is unable to transition between the on-state and off-state positions.
