Quick Answer: The Optical Bench Ordinary is a simple bench for arranging lenses, mirrors, light sources and screens in a straight optical path, used in focal length and image formation experiments.
Last updated: October 2026
Key Features
Bench-style layout for straight-line alignment of object, lens, mirror, screen and light source.
Holders move along the bench so positions can be read and compared.
Used for finding the focal length of convex lenses and concave mirrors.
Supports work on the lens formula and magnification.
About This Product
Students fix the holders they need on the bench, line everything up on a common axis and then slide the lens, mirror or screen until the image is sharp. Reading the object and image positions from the bench scale lets them calculate focal length, magnification or image distance, linking optical formulae with real laboratory outcomes. Handled carefully, the bench can be used repeatedly in classroom labs.
Frequently Asked Questions
Q1. What does the bench help students measure? Object distance, image distance and the positions of optical components, from which focal length, magnification or image distance are calculated.
