IR receiver window

  1. Looking for a source of supply for a small dark red sensor cover for an IR
    receiver similar to that used on a lot of commercial equipment.
    The IR module is mounted behind an aluminium panel with a 5mm round hole
    drilled through it to allow the IR signals to pass through it.
    What I need is a suitable small "window" or sensor cover to provide a
    finished look to the product. The hole can be made larger to accommodate a
    bigger cover if necessary.
    Anyone sells these?

    Thanks,
    Alan

    Pickup an old VCR, DVD, CD, TV from the roadside and remove it from there?
     
  3. If worst comes to worst (and I'm guessing you're not going to find something
    like that as a spare part), acrylic.

    Any colour at all, while it's opaque to visible light, it's transparent to IR.

    I have a bundle of red acrylic strips 74mm x 7mm x 0.254mm originally intended
    for led window if you can find a way of mounting.

    just buy a couple of small cctv replacement domes , one of those will
    make hundreds of windows for a couple of bucks
     
  6. Tooling costs wouldn't make it cheaper than a large sheet of acrylic cut
    into little rectangular squares. Circles would cost more, but you need to
    evaluate the tooling on the box too. Rectangular holes in a box are more
    costly than a simple hole. Need to get the calculator out and do some adding
    here.

    It really doesn't need to (and shouldn't) be fancy. Heck, the trend on
    remotes is to mould a hole into the plastics and simply poke the IR led out
    directly.

    At the receiving side, the fancy window is integrated into the display
    panel, so you don't need a separate window for the IR receiver, and double up
    on the use of the translucent window for the display that needs to be there
    anyway.

    You're hands would be tied if the case is complete except for the IR hole,
    but that would more than likely show bad engineering behind it. (and a
    distinct lack of forethought).

  8. If you are happy to cut yourself, Jaycar have red perspex - HM9505
    $9/sheet from Electus.

  9. Thanks Dave,

    Quite a good alternative to a commercially made window and I can cut a heap
    of them from a sheet that size.

    Cheers,
    Alan
