I will check with folks at the East Bay Astronomical Society up at Chabot Space & Science Center. There is some amount of spectroscopy equipment around up there. Though much of it is very old, and intended for astronomical observations (attached to a telescope), something might be useful, and there might be someone who is interested in helping out.

Thanks. I appreciate it. It turns out what we need is a visible light monochromator. Also, light meters with good sensitivity at low levels would be helpful as well. Biology labs often have monochromators. A spectroscope would be helpful to validate light sources, if a monochromator cannot be found and one would have to be fabricated.
