Optical Surfaces has supplied several sets of ultra-high quality plano-convex lenses to the MAX IV Laboratory.

The students performed various experiments in remote mode — from physics experiments such as calculating the gravitational constant g using a pendulum to finding the focal length of a convex lens.

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...
