Removing the optical module from the DLPDLCR2010EVM

Other Parts Discussed in Thread: DLP2010NIR, DLPC150, DLP2010, DLPC3435, DLP4500NIR, DLP4500

Hi,

I am interested in the DLPDLCR2010EVM development platform, mainly to get my hands on the DLP chip itself and the accompanying control board. In our envisioned setup the illumination would be provided by an external laser, so that we don't need the rest of the optics that come with this development platform.

My question is, whether it is (easily) possible to separate the optical module from the DLP and the control board. If this is the case, we would then like to mount the DLP on a home-made support. For this to work the DLP must be connected via a (reasonably long, maybe at least 5cm) cable with the control board - can you confirm this?


The laser wavelength we are using will be 780nm, so outside the given range of wavelengths for the DLP. Is it possible to order this development platform with the NIR version of the DLP? If not, could we order it separately and later exchange them?

Thank you very much in advance,

  Kilian

    Hello Kilian,

    Our controller on the DLPDLCR2010EVM is not supporting the DLP2010NIR. To be able to use the DLP2010NIR you need to have the DLPC150.

    In the near future there will be an EVM for the DLP2010NIR which will probably fits your needs better. Please take a look at following link:

    Please let me know if you have any further questions.

    Thanks,

    Hi Nadine,
    Thank you very much for your quick reply!
    Since we would like to buy the DMD quickly I don't think we can wait for the arrival of the EVM for the DLP2010NIR. Even though the VIS version of the DLP2010 is not rated for 780nm, we think that it would work nevertheless (we only need very little intensity reflected from the DMD, so that losses due to the inferior reflectivity would not be so bad).

    I would therefore like to ask you again whether it is easily possible to separate the optical module from the DLP and the control board, and whether the DLP is connected to the control board via a reasonably long cable.

    Thank you very much in advance,
    Kilian

    Hello Kilian,

    Yes, you can remove the optical module from the DMD. The DMD will be probably glued in so it will be a little bit tricky but you can use a separate DMD and connect it to the flex cable. Please keep in mind you also have to connect the flash device which is currently mounted on the optical module.

    The flex cable has an L-shape. The first length is 4.2 cm coming out from the board connector and the second length after the turn to the optical engine is 4.7 cm.

    Best regards,

    Nadine

    Hello,

    I see that this question was posted more than a year ago, so I am interested in an update.

    I would like to get started with the DLP2010 development kit (LightCrafter Display 2010 EVM) to verify the functionality of the DLP and to verify my use of the software. After some initial testing, I would like to remove the optical module and use the DLP2010 (still controlled with the development board) with my own custom optical module.

    So is the DLP2010 easy to remove from the optical module of the development kit without damaging anything or altering its functionality?

    If I buy a separate DLP2010 (part number DLP2010FQJ), can I connect it to the end of the flex cable on the 2010 EVM development kit, and it will function properly?

    Thank you!

    Hello Kevin,

     

    In general, the DMD (DLP2010)  can be removed from the optical engine but may not always preserve the DMD itself. You may void your warranty in doing so, as well. it is recommended that you consider getting a separate DMD to test your optical engine.


    Generally, there is an interface between the flex cable and the DMD in the optical engine. Without this interface the DMD will not work.

     

    Let me know if you have further questions.

     

    Best regards,

    Hi Philippe,

    I was reading this post from November. So, I understand the DLP2010 can be removed and replaced (if done carefully). My question is, how difficult is it to replace the DLPC3435 Controller with the DLPC150 Controller?
    Also, how does this effect the programming interface with the device?

    We are buying the DLP Lightcrafter Display 2010 and we are hoping we can get it to work with the DLP2010NIR.

    Thank you,

    Hi Angie,

    I saw you replied to this thread that I started, and thought that it might be useful to you to know for which solution we finally settled:

    Instead of buying the DLPDLCR2010EVM development platform, getting rid of the included light source and trying to unglue the DMD, we found a supplier that just provides a "bare bone" version of driver board plus DMD:

    www.keynotephotonics.com/.../

    We bought a LC4500 driver board, LC4500 DMD board, and a DLP4500NIR DMD. The prize is about the same as the development platform, and we didn't have the hassle of having to unglue the DMD, potentially damaging it.

    This is not the same DMD that you mentioned - I don't know of course whether for your application the DLP4500NIR would also work.

    I hope this helps.
    Cheers,
    Kilian

    Kilian,

    Thank you so much for your help! We are looking at both the DLP2010/NIR and the DLP4500/NIR as options so that could be a very good solution for us as well.
