50mm Acrylic Demonstration Lens Set
by United Scientific

Each lens in this set made of acrylic, and is 50mm (2 inches) in diameter. Their size and light weight make them perfect for use with an optical bench, or for basic optics demonstrations, which can include things such as building homemade magnifiers and telescopes, or experimenting with laser/light. The entire lens set comes boxed in a convenient storage box, to prevent them from being damaged when not in use, as well as for holding the set to keep them together. Also included is an activity guide, which gives detailed instructions for conducting experiments with the lenses. This set does have an approximate focal length of 150mm (15cm/6 inches), though this set is not intended to be focal length specific.

Included in every demonstration lens set are the following lens types:

• Double convex
• Double concave
• Plano convex
• Plano concave
• Concavo convex
• Convexo concave
