L6-21: OPTICAL BOARD - DIVERGING SPHERICAL LENS

ID Code: L6-21
Purpose: Determine the focal point of a concave lens.
Description: Parallel rays incident on a diverging plano-concave spherical lens appear to emanate from the focal point of the lens. Two diverging lenses can be placed together to increase the divergence and decrease the focal length. A slit baffle with concave and convex lenses are used to create the set of parallel rays, which can be varied in number and in spacing.
