Flexible opaque black material

  1. Dec 3, 2015 #1
    I'm looking for a material to use as a light shroud for a joint between a spectrometer and camera. Basically, I want something that is flexible, opaque, black, and fairly thin and not too fragile and something I can readily buy. Do you know any such material? I have used Poron foam before which works ok but I'm wondering if there is something better.

    I use closed-cell neoprene foam. Used as a gasket, when lightly compressed it is very effective.

    PVC electrical tape is completely transparent beyond about 900nm - you can see right through it with an IR viewer, so I would avoid that.

    Hrm. OP didn't mention IR.

    Perhaps we could use more details.

    Oooo that back-fired, didn't it? I was only joking, of course; I don't really take it.

    At least, not since the court case. My probation officer won't allow it.

    Still joking. REALLY! JUST JOKING!
