i have managed to acquire 3 rear projection TV lens's, from a CRT type tv. these have 3 total lens' inside the housings. 1 main middle convex lens and 2 what look like fisheye lenses, (1 on each end), then there was a liquid lens mounted directly to the CRTs themselves but that lens was left behind for obvious reasons. Anyone here know a way to use these loose lens' in a spotlight effectively?
any and all advice would be welcome as i have not worked with lens's at all as far as spotlights go.
