50mm Glass Mirror Set for Optical Demonstrations – Set of 6
by United Scientific

This set of six glass spherical mirrors comes with a silvered back surface. Each one measures 50mm (5cm/2 inches) in diameter, and they all feature a different focal length. There are three convex, and three concave, mirrors in the set, and each one of them comes in its own small storage box, and is wrapped in protective paper to keep them from becoming scratched and broken. A larger box easily fits all six mirrors, allowing the set to be kept together all in one place.

The different focal lengths allow for a wide range of experiments to be conducted, both with and without an optical bench. The convex mirros have a focal length of 50, 100, and 200, while the concave mirrors are -50, -100, and -200.
