The EISCO 6pc Optical Lens Set includes three double convex and three double concave lenses, each with a 3" diameter and varying focal lengths of 200mm, 300mm, and 500mm. Made from optically true glass with ground, beveled edges, this set is ideal for educational purposes, particularly in physics classrooms, to demonstrate principles of optics and light refraction.

Quality is great
Quality of these lenses are noticeably better than some others I bought at same time for about same price. They are nicely ground and very scratch resistant. I beat them around and thought I scratched or even broke them a few times during testing my product and they remain in perfect shape. Great value for what they are!

Was expecting more, even given the price.
I do not know what I should have expected from "Optical glass blah blah", but the lenses are not polished properly. They are grainy.
