DLP2000: Is it possible to use only the DLP of the DLPDLCR2000EVM board, removing the projector?

Part Number: DLP2000

Hello,

I am interested in using a Digital Micromirror Device (DMD) to perform an experiment using a laser source. The goal is simply to control a few micromirrors of the DMD in order to reflect part of a laser beam.

With reference to the DLP® LightCrafter™ Display 2000 Evaluation Module. Is it possible to remove the projection part and use the DLP only for light reflection purposes?

Best Regards,
Tiago Magalhaes.

  • Hello Tiago,

    In general this DMD is designed for display applications with an LED illumination source. While you may be able to remove the optics yourself (this will void your warranty) you will need to ensure the electrical connection is still made to the DMD so it can be properly powered and controlled.

    Thanks,

    Tiago,

    Welcome to the E2E forums and thanks for your interest in our DLP technology.

    As Kyle states above, it may be possible to disassemble the optics and replace the LED source with a laser. However, I would note that the DLP2000 DMD has not been rated for laser applications. You should review the DLP2000 datasheet to see what specifications you light source should follow for optimal performance. You may experience reduced lifetime with this system configuration.

    I hope this helps.

    Thank you for your and reply.

    I have two more questions.

    1) In principle, if I just remove the LED source and substitute it by another light source, would the software function normally?

    2) Is there any similar product, when comparing to the DLP® LightCrafter™ Display 2000 Evaluation Module, where only the DMD is present (without the optics and the LED source)?

    Tiago,

    If you use a similar light source you may be able to get the system to still work. For instance, you might be able to swap one of the LEDs for a different colored LED. However, you won't be able to switch the LED for a laser or lamp.

    At the moment we don't offer any EVMs in this price range with no optics. You would need to design a flex and mount for your DMD to work standalone.

    I hope this helps.
