Spectral Distribution Glasses

  1. I'm cleaning out some old piles of paper in my office and
    came across a pair of spectral distribution glasses that
    Philips gave out at a Light Fair or IES meeting, probably
    around 2000, based on the "layer" in which they were found.

    These look like 3-D glasses, but resolve the SPD of any
    light source the wearer looks at. Rather neat, if you can
    find a pair.
