| 727414 | 2008-12-10 07:33:00 | How to Measure magnification How can I see how strong a magnifying glass is? I bought this magnifying glass [edit] and I want to know how to test it to see how strong it is. I hear a lot of people talk about magnifying and how strong the magnification is, but I would like to know the true magnification of my magnifying glass. I have a few of them and some seem stronger then others. How can I rate these? How can I pin a correct number on mine? How do the companies that make these come up with these numbers. |

| 727419 | 2008-12-11 03:45:00 | It's to do with the focal length. Set up a light source an infinite distance away :) and see where the light focuses. Measure the distance from this point to your magnifying glass, and you have the focal length. The shorter it is the "stronger". | shermo (12739) | ||

You must have thought I was being incredible rude with my reply otherwise. :p |
