Guess physics is the best forum to put this under as it's an optics question.
I have a thermal gun that has a distance to spot ratio of 9:1 which is actually moderately decent as far as thermal guns go, but I've run across the problem than even right at the outlet of the gun it's not focused properly for anything less than that 1 square inch area, making it completely useless for checking individual transistors or surface mount packages which is really what I had in mind when I got it.
I've seen close focus (.1 inch spot size at 1inch) IR guns, that are EXACTLY what I need but I've also noticed that the aperture of my thermal gun is threaded, which I'm sure they meant for coupling of a focusing element of some kind.
Can anyone provide any tips on if I can use standard glass optics as a focal element to try to refocus to the smaller spot I need?
