Filtering ultraviolet from Xenon arc lamp

  1. Oct 4, 2013 #1

    What sort of commonly accessible material can block harmful UV from a 150W Xenon arc lamp, without blocking much of visible light?

    Lamp relative spectrum (a bit around 250nm, growing to a lot at 400nm):

    Enough UV should be blocked for the lamp to be usable as a regular household light source.

    UV filtering on the cheap

    Try a piece of polycarbonate. It's dirt cheap and it inherently filters out most UV.
    Even the cheapest sunglasses can claim to block 100% of UV because they just use PC lenses.

    Common trade name being Lexan.
