Ball Lens on First Floor



This ball lens is quite large, isn’t it? It’s not likely what you think of when you hear the word lens. You probably think of a pair of eyeglasses when you hear the word lens, but this large ball and some glasses really do have a lot in common. All a lens is a piece of glasses with precision surfaces cut and polished on either side of it. The thickness, shape, and type of glass all contribute to how powerful of a lens it is. There aren’t really two sides to this particular lens since it’s a ball, but the idea is the same! You can see it act as a magnifying glass as you hold up objects to it, or even if a friend puts their face on the far side of it from you. Give it a try! This lens was polished here at the college and was donated by O’Hara Glass.
