Maximum illumination

Hello,

I read from the 0.7" 2xLVDS XGA document that the maximum illumination is: 25 W/cm^2  for the wavelengths between 400nm - 800nm using a CW source.
It also has a rating of 0.68 mW/cm^2 for wavelengths below 400nm.  Is this still true for the UV coated DMD? 

Our wavelength of interest is 355nm.

Also, is the 2xLVDS (D4000) rated differently than the LVDS (D3000) for maximum CW illumination?

Thanks,
Jason

    The DMD designed for UV applications allows much more UV than 0.68mW/cm^2.  There are many applications at 355nm.  Let me check the specification.

    Jason,

     

    It is true that the DMD is used in many applications where high power UV light illuminates the DMD.  TI has enabled the applications by modifying the window to allow the UV light (320nm-395nm) light to pass efficiently.  To this point, these parts have been sold without qualification of the operating conditions allows customers to experiment and develop new uses with the DMD.  Some applications are known to operate at power levels of > 3W/cm^2.  TI intends to publish a document specifying the DMD performance under UV conditions in 2Q09 based on testing completed by TI.

     

    Let us know if you have anymore questions.

    "Some applications are known to operate at power levels of > 3W/cm^2."

    That is good to hear.  Thanks for the replies.

    "TI intends to publish a document specifying the DMD performance under UV conditions in 2Q09 based on testing completed by TI."

    Has this document been published yet?
