Description

This device demonstrates “Newton’s Rings,” colorful interference fringes caused by a thin air layer first discussed by Isaac Newton in a communication to the Royal Society in December 1675, and presented an expanded account in his book "Optics" (1705). The original observation was first made with a wedge-shaped air-gap between the surfaces of two prisms, but later used the now-standard technique of pressing the convex surface of a lens against a flat glass plate.
