DLPDLCR2010EVM: Making a projection system with custom illumination sources

Khaled Ibrahim

Part Number: DLPDLCR2010EVM
Other Parts Discussed in Thread: DLP2010

Hello,

I am currently working on building a projection system based on a DMD, and this evaluation board seems fitting for my application. There is just one issue, I need to illuminate at specific wavelengths (565 and 730). So, I was wondering if the best option is to buy this module and somehow deactivate the built-in LEDs, and instead use other LEDs with the wavelengths I mentioned. Or, is there a better option, like buying the DMD separately and building from there?

Thanks a lot!

    Hello Khaled,

    Thanks for your interest in our DLP Technology.

    The DLP2010 DMD is not rated for these wavelengths. In particular, you should review in section 6.4 of the DLP2010 datasheet www.ti.com/.../dlp2010.pdf which shows the maximum power density for various light wavelengths.

    Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination will
    reduce device lifetime

    We have a family of products that are optimized for UV-wavelengths. If you are interested in checking them out, go to our UV products overview page www.ti.com/.../overview.html.

    I hope this helps.

    Thanks,
    Navneet

    So, is it completely impossible to use this DMD at the 730 nm NIR wavelength?

    Is there any DMD that would support both 565 and 730 nm illumination?

    And, could you let me know anyway the best way to use a DMD with custom illumination sources? Would it be simpler to get the evaluation module and customize it, or to get the DMD separately and build upon it? Would the latter case need me to design a PCB?

    Thanks a lot for your help.

    Khaled,

    Every DMD has its illumination wavelength range.

    Unfortunately, we don't have any DMD which support this illumination range 565 as well as 730. For better understanding of illumination wavelength range i suggest you to check our products page online.

    NIR : www.ti.com/.../products.html

    High Speed Visible : www.ti.com/.../overview.html

    You can customize the illumination on EVM module untill it stays in illumination range.


    Thanks,
