Practical question: Will placing a clear UV filter over a magnifying lens inhibit the ability of that lens to focus sunlight to the degree necessary to produce fire?
I have a window with several "bullseye glass" panels in my home and have noticed that when the bright winter sun passes through at just the right angle, these panels produce a beam hot enough to get the upholstery smoking! Seems like a fire hazard and I'm wondering if applying the UV blocking film sold at home centers will fix the problem.
