picco 0.17" DMD Efficiency in NIR?

Liang,

The DMD WIndow Transmission (not inlcuding mirror reflectivity or diffraction effects) is basically the same as the Type A window coating.  Please see the attached link:

The Window transmission for the "Visible" AR coating on the pico DMD will be 70-80% efficent from 900-2400nm, as shown in the chart.
