Measuring magnification
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.

hellogreen, if you contact lanely, (shouldn't be too tricky) I think you'll be able to occupy each other for a while.

). The magnifying power of a magnifying glass is solely a function of the focal length of the lens. To measure this, simply image a distant source (the sun comes to mind if you can wait until it comes out again) on to a plane surface then measure the distance of the lens from the surface when you have the sharpest image. that is the focal length of the lens.Hope that helps and that you don't choose a flammable plane surface to work with.
<jeez, what sort of question was that? In the main forum no less>

Interesting first post, that. However I'll leave the ribaldry to others (this time ). The magnifying power of a magnifying glass is solely a function of the focal length of the lens.
