DLPDLCR2000EVM: Minimum Focusing Distance

Part Number: DLPDLCR2000EVM

What is the minimum focusing distance achievable using DLPDLCR2000EVM ?

Also, Can I use it without Beaglebone and connect it to PC via HDMI to display images?

  • Ali,

    Thanks for your interest in our DLP products.

    According to the specifications the projection image size ranges from 10" to 60", and the system has a throw ratio of 1.6. By these metrics I calculate that the system has a minimum focus distance of 13.92".

    The system can be used without a BeagleBone, but may require additional development work. In particular, this EVM does not have an onboard HDMI interface. However, all of the parallel video pins are fully exposed, making it easier to create a custom adapter interface. I recommend you review the DLPDLCR2000EVM User's Guide at www.ti.com/.../dlpu049 for a detailed description of the parallel interface in question.

    I hope this helps.

  • Hi Philippe,

    Thanks for the info. Is it possible to replace the lens in order to modify the focusing distance?

    I am aiming for a focusing distance of 4-6"

  • Ali,

    It seems that the lens on the DLPDLCR2000EVM's optical engine is not made to readily accept different lens installations. However, it may be possible to modify the optical engine by adding an extra lens in front to shorten the focusing distance.

    If you are interested in this modification I can get you in touch with one of our optical engineers who can assist you with implementation.

  • Hi Philippe,

    Yes please, if you can ask your optical engineers to help me with this implementation then it would be great.

    Thanks.
