  • DLP4500NIR: for mid-wave infrared applications

    TI Thinks Resolved
    Part Number: DLP4500NIR Hi there, We need a DMD for the mid-wave infrared spectral region up to about 3.5 or 4 um wavelength. In the datasheet of DLP4500DLP, the window transmittance is reported up to 2.5 um. Do you have the transmittance values for...

  • DLP4500NIR: DMD as a only-amplitude Modulation device

    Part Number: DLP4500NIR Dear TI engineer I had seen the application about DMD as a only-amplitude Modulation device,but I don't know how to accomplish the process,Can you help me?

  • RE: DLP4500NIR: Beam shaping algorithm

    Hello, Yes, it should be possible to shape a laser beam arbitrarily with a phase-only SLM. We don't have any past work inside TI on this subject. There are are several papers that discuss how to do it. One such reference would be a PhD Thesis...

  • RE: DLP4500NIR: 4 diffraction patterns are generated from ON state

    Hello Vincent, The equation is correct. However few values are not correct - Pitch - It will half of pixel diagonal i.e. 7.56 x sqrt(2)/2 ; it distance between two vertical rows of pixels or distance between two closest tip of pixel. m - please...

  • RE: DLP4500NIR: Diffraction Efficiency plot

    Hello Vincent, Please accept my request to connect so that discuss your requirement and experiment details offline. This way I can provide best possible response & support. regards, Vivek

  • RE: DLP4500NIR: Selectively Park DMD Mirrors

    Hello Burkley, Unfortunately this is not something we can support. The DMD is intended to be a bistable device. I have sent you a friend request on E2E in case you are able to go into any more detail in a non-public setting. Thanks, Kyle

  • RE: DLP4500NIR: DLP4500NIR and gray scale video

    Hi Alexander, You can display three 256 level grayscale images from 24bit input in pattern mode. However, you need to note the following points: The DMD shows bitplanes in a Time Division Multiplexing scheme. So the grayscale levels will be achieved...

  • RE: DLPNIRNANOEVM: Extending range on NIRScan Nano to 2500nm?

    Thanks Phillipe, thanks what I thought. Not sure what why the DLP4500NIR is even listed on the Nano page if its not even applicable,its just confusing. Thank so much for taking the time to answer the post. Best, Matt

  • RE: DLP4500NIR: Pixel flight path as a function of time, or control of dithering frequency

    Hi Blake, Thank you for your patience. The mirror transition speed is very fast compared to the pattern rate (4K Hz). The typical flight time for the mirror form one sate to another is 1-2 Microsecond and followed by 4-5 microsecond settling time. ...

  • DLP4500NIR: DMD total efficiency : LED vs Laser

    • Resolved
    Part Number: DLP4500NIR Hi, I'd like to know DMD efficiency as below case. DMD : DLP4500NIR / Light
