I am 15 years old ( 10 grade) and just joined the forum. I am interested in doing a science fair project where I can test the intenisty of the laser beam after it travels through different types of lenses. I was thinking of using the IR thermometer I have seen used on this forum as a laser power meter to measure the effect on the beam strength (intensity/thermal output) ) after it passes through various lenses. I am hoping some may increase the strength and others lessen it. At least that is my initial hypothesis. I plan on purchasing some lens assortment from Meredith instruments for $25. I hope they have some of the following:Bi-Concave, Bi-Convex, Plano-Concave, Plano-Convex lesnes in the kit. My thought if I use a laser pointer or somehting inexpensive like that I would be simulaitng how I think a cutting laser works with an external lens concentratiing the beam strength to cut the metal.
Anyway I may be over my head here and am not making much sense. I would appreciate any help, ideas, suggestions or resources on how or where to get materials, etc. to do my experiment.
Thanks
