Incident Angel Wavelength

Renan Santos Adriano

Hi Team,

My Customer is looking at our (1) DMD working at 400-700nm, does the incident angle wavelength-dependent? and does the incident angle sensitive? (2) can a  DMD reflect a broadband light source say 500nm - 900nm? Any inputs are appreciated.

Regards,

_Renan

    1. Can a DMD reflect a broadband light source say 500 nm - 900 nm?

    TI DLP manufactures DMDs with performance optimized for three different optical bands

    High speed visible nominally 400-700 nm
    Near-infrared (NIR) nominally 700-2500 nm
    Ultraviolet (UV) nominally 363 - 420 nm

    Depending on the customers system performance needs, either a visible or NIR DMD may work for 500 nm - 900 nm operation

    See http://www.ti.com/dlp-chip/overview.html

    DLP application note DLPA031 has details regarding the optical performance of each window design

    See http://www.ti.com/lit/an/dlpa031d/dlpa031d.pdf

    2. Incident angle wavelength-dependent?

    Incident angle of the optical source is typically not wavelength dependent. Incident angle is a critical optical design parameter to achieve the best optical performance.
