United Scientific Supplies Introductory Optical Bench Set

Description

• This introductory bench set allows the basic properties of lenses to be explored
• The optical elements are mounted in robust molded holders that are pushed into sockets in the riders
• Each rider can accept up to three elements
• The riders slide freely on the aluminum bench until an optical element is pushed in, when the rider locks in place
• This eliminates accidental repositioning allowing the entire lightweight setup to be carried around without anything falling off
• The LED-illuminated object is self-contained (powered by an AAA battery– no cables) and generates bright, clear images on the opaque screen
• Four high quality lenses are included, all with 50 mm diameter
• The focal lengths are, +100 mm, +150 mm, +200 mm, (all convex) and– 150 mm (concave).
