(meteorobs) Transmission Grating Material
I'm looking for samples of in-expensive transmission grating
material, mounted or un-mounted, about 2 to 3 inches square. I want to test
these to see if they would work for meteor spectroscopy. I can compare the
samples to my precision B & L, (Richardson Grating Lab), grating. Precision
gratings are rather expensive so it would be nice to find an in-expensive
grating that would work. I have already tested a sample that I have, but
unfortunately it prooved too inefficient for meteor work. Perhaps there are
better samples out there. If so send me a piece along with the specs, cost
and where you got it. Any samples sent will not be returned but I will
report on whether it will work or not. Ed Majden
