  • Forum Post: Re: DLP Light Commander light source

    TME -RL
    Andrew, One of the design guys pointed out that the actual output of the LightCommander will be significantly less than that. They have asked for testing to be done to give a ballpark number. I have not seen the results of that test, but it will be on a subset of the first builds to go to distribution...

    Daisuke Iwai Can I replace the illumination source to UV-LEDs to produce UV projector? Yes, you can do that, however you will also need to replace the optics with UV capable optics. The standard glass optics in the LightCommander will not be as effective as a set of optics designed to work...

    Jack, The DLP Discovery 3000 kit is no longer available. Please look at the DLP Discovery 4100 Kit. Go to http://ti.com/mems and click on the link "Developer Kits" under "Getting Started". The Discovery 4100 offers the same DMDs as the discontinued Discovery 3000 kit. The Discovery...

    Raphael, Welcome to the DLP & MEMS E2E forum. I recommend that you get a Pico Kit V2. The distributors are showing these as not available at the moment. Please try again towards the end of March. Also, please consider the DLP LightCommander Kit. It features a 0.55 inch, XGA (1024x768) DMD...

    Markus Greiner
    Hi, I would like to use the DMDs unique speed and precision for a spatial light modulator application. The DMD will be placed into the fourier plane. Unfortunately it seems that the DMD chips are not particularily flat, the wavefront distortion is on order 10 fringes , as can be measured interferometrically...

  • Forum Post: Using laser light with DMD DLP chip

    Sean Willcott
    I have been reading this forum looking for others that have tried using infrared laser light, specifically CO2 laser light about the 10.6 um wavelength, and have not found what I am looking for. From what I can gather, the 0.55 XGA Series 450 DMD does not handle NIR light, but the 0.17 HVGA DDR Series...

    Yuma Tsuboi
    Hi, I am working with the DLP LightCommander 5500, and am having trouble with the failure of the red LED. I later found the errata E0031, where it describes that premature failure of red LED(or sometimes the other colour) will occur when the light intensity setting is set to greater than 60%. Since...

    Pascal DLP
    Weirong, I'm not sure I exactly understand your question about the "optical power" of the Light Commander and the Pico Kit v2. However, you may be asking about their brightness. The Pico Kit v2 is about 8 lumens. The Light Commander is up to about 200 lumens. The Molex connector can...

    Simon Speiser
    Hi, i'm new to this forum, but I couldn't find some clear information the Lumen rate of the LightCommander. Are there some test-results about this? I would be specially interessted in the Lumen rate reached in the Binary Pattern Mode. Thanks a lot!

    Hi. I am confused about [Frame rate] which is used in [Lightcommander Control Software]. So please tell me about detail about that. I thought that [Frame Rate] is used for changing the frequency for each pattern's changing timing. But when I changed the [Frame Rate],transfer them to board,play...

    Pascal DLP
    Wayne, Welcome to the DLP&MEMS E2E. First - the Nikon 18-55mm f3.5-5.6 DX lens will work fine on the LightCommander. My only concern is the relative dimness of the lens when compared to the f/1.8 of the supplied 50mm lens. The crop factor really has meaning only in the context of comparing...

    Pascal DLP
    Hello Anthony, Are you sure that you have opened the aperture on the lens to its full open position (f/2.8)? I don't know if this lens has a manual aperture ring, or if the aperture is controlled by the camera electronically (I have no experience with this lens). However, I am sure that if it...

    Pascal DLP
    Anthony, Are you trying this with the R G B LEDs (white) on? Does the output from the LC look bright? Have you tried another lens - of a different focal length (the supplied 50mm f/1.8)? Is the image as bright (visually) as you would expect with that lens? Have you measured it with the photodiode...

  • Forum Post: Re: Flex cable between DMD and controller board

    Pascal DLP
    Salih, You mention rotating the DMD+Controller board by 45 degrees. If you are not going to use the LightCommander optical/illumination system, then it is quite possible to mount the controller board at a 45 degree tilt, with the DMD board plugged in, and secured by a suitable bracket. This can be...

    Pascal DLP
    Anthony, I do not know the answer to your question. I have not attempted to do this. I am pretty sure that the issue has to do with the NA (or angle of acceptance) of the microlenses. A spec sheet of the microlens array would be helpful. I believe that the microlens array probably expects the incoming...

  • Forum Post: Re: DLP with Violet LED?

    Pascal DLP
    Riccardo, As you point out, the DLP5500 DMD used in the LightCommander is spec'd only for 420-700 nm. All of the violet LEDs in the link you provide (I looked at the datasheet) are shorter than 420 nm). So, it would not be within the TI data sheet limits for the DLP5500. It may indeed possible...

    Hello TI tech support, I want to ask a question regarding a problem I am having with the LightCommander projector. The problem is that when projecting images that have smooth intensity/color gradient, the projected image shows discontinuities in the intensity/color. For example, if I project an image...

    Hello TI tech support, When I use a white image, i.e. all the pixels are “ON”, the captured image reveals a non-uniform behavior of the light coming out from the LightCommander. I have done several tests and consistently got the same behaviour for different frame rates. The projected image...

    Travis, Welcome to the TI DLP&MEMS E2E forum. The DLP LightCommander comes fitted with a Nikon F lens mount. This fits all standard Nikon F-mount lenses, such as the one supplied with the LightCommander kit - a 50mm f/1.8 Nikon lens. I found the following adapter: http://www.amazon.com/Fotodiox...

    Pascal DLP
    Thank you, Stephen. That is helpful - and right on. Travis, First, I don't think that a fisheye is what you are looking for. Familiarize yourself with rectilinear vs. fisheye rendering. They are very different. Ideally, you want rectilinear rendering, with a low distortion as possible. Stephen...
