hellogreen Posted December 1, 2008 Posted December 1, 2008 How to Measure magnification How can I see how strong a magnifying glass 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. Quote

CarlB Posted December 1, 2008 Posted December 1, 2008 Read the wikipedia entry, it describes how magnification is "measured" by distance to best focus. It doesn't sount too precise. http://en.wikipedia.org/wiki/Magnifying_glass I found a more in-depth discussion at http://www.myoptica.com/helpoptics.cfm Quote
