Regarding Anita Robert's inquiry at:

Anita:

The large apparatus you have discovered is a very nice, expensive spectroscope.

See:

to see what one looks like that uses a diffraction grating for breaking
light down into it's component colors.

At:

http://www.daedalon.com/optics.spectrosc.large.l.jpg

you'll see one that is designed so that you can use either a diffraction
grating or a prism (the old-fashioned way) for the same purpose.

I believe the latter is what you have come across.

The holder for the diffraction grating is probably lying around in a box
somewhere in your lab. If you are lucky, you'll find another box that
contains the prism. The prism would be sandwiched between the two plates.

Happy hunting.
