lenses / objectives / mirrors for below 405nm

Frankenscope? Let's see it!***be advised that NOTHING in this forum has been safety tested and you are reading and using these posts at your own peril. blah, blah, blah... dont mess around with your eyesight when it comes to solar astronomy. Use appropriate filtration at all times...

How far into the UV do you want to consider?
I have successfully imaged stellar spectra with a Genesis and ATiK 314 down to 375nm.
You also have to consider the CCD response in the UV......

I would include the Takahashi TOA 150 (down to 350 nm).
If Balow lens are to be included, I would add Baader FFC. (down to 350 nm).

I don't know whether this is relevant to the post, but I have OSLO simulations of a variety of Barlow lenses down to 350 nm:
