Will a windshield repair kit fix a dinged condenser lens?
I accidentally dinged the flat side of a condenser lens with the edge
of another lens, made a small gouge probably a couple of 1/1000ths " deep give or take - I can feel it with a fingernail - and it's quite visible when projecting an image through it. Will one of these windshield repair kits with a sunlight hardened resin make the ding optically invisible - i.e. so that it doesn't cast a shadow when projecting through it, or is pointless to try? Don't want to spend the $11 if it's not going to work. Is there any kind of repair material for this kind of thing? If that method isn't going to work, it's my understanding DIY lens grinding is possible. Do you think it would be possible to grind down the flat side of the lens past the point of the damage? Any links to directions on how to do it? Where's a good place to get materials to do this? I know, the lenses aren't expensive but I hate to waste an otherwise good one. I assume it would change its focal length slightly but it's probably not crucial for my purposes. Thanks for all input. |
