Stanhope lens

Have you ever tried to look at something very tiny, like an ant or a grain of sand, but it was too small for you to really see well? A stanhope lens is like a tiny magnifying glass that can help you see small things better!

The stanhope lens works by curving the glass in a special way that makes things look bigger when you look through it. It's named after a man named Rene Dagron, who made small photographs called "microphotographs" that could only be seen clearly through very small lenses like the stanhope.

So if you have something very small that you want to look at, a stanhope lens can help you see it better!
