Does anybody have a supplier for long 90-degree prisms (say,
1"x1"x12")?


Try the Klinger Educational Products Company
112-15 14 Rd
` College Point, NY 718 461-1822

They have one about that size in their "Blackboard Optics" set.
and I'm sure that they will be heppy to sell one at a very reasonable
price without having to purchase the rest of this entire $500 set.

I'm working on making a lab for students to determine the albedo of
the moon
by comparing spectra of the sun and moon. As a secondary goal, I
have this
thought that the spectra off a reflecting body should be a bit
different
than a straight-shot spectra. Is there any truth to this??

I thought I could get clear of the "you'll burn your eyes out!"
arguments by
simply projecting the spectra onto a sheet of paper for the students
to
marks where the absorption lines were, hence the need for a long
prism.
