(meteorobs) RE: UV lenses for spectroscopy...

[Swift, Wesley]

Ed,

	Just found this:
  http://www.a1.nl/phomepag/markerink/uv-lens.htm  

It appears that "EL-Nikkor lenses are designed for ultraviolet transmission
in the 350 to 450 nm range."  Enlarging lenses are easy to find if a bit
awkward to mount, particularly to a Canon.

	Interesting:

These guys are extreme: On the UV lens page they promote grinding off the
lens coatings!

Of course, there are numerous sources for military grade UV lenses at
astronomical prices.
