Newton Ring Newton Circle School Physics Optical Interference Teaching Instruments

One of Newton’s experimental devices is about light interference. The general structure is two circular glass plates that are stacked together. The lower layer is flat, and the upper layer is an arc-shaped curved surface, so as to produce a layer of air with a gradual change in thickness. The propagation in the air layer is a change in the optical path, and the interference intensity also changes, so the interference pattern can be seen

Large ring diameter 5 cm, small ring diameter 3 cm, height 2.5 cm.

Model No.:HTP-094
