Depends on your use. Overhead illumination would work but would be
slightly less sensitive. Maybe you can find someone with a cracked
filter that you can cut down for your own use etc. 

Whatever you do make sure you have at least eye protection and
preferably full face visor. For photographic or CCD use a photographic
UV filter plus orange filter. 

My mind's made up. Don't confuse me with the facts!
