Haidinger Fringes

In the relation if t is large a very small change in will change the path difference by one wavelength. In this case the ray must pass through a plate as a parallel beam and must be received by the eye or the telescope focused for infinity. The interferences patterns are known as fringes of equal inclination. These are different from Newton’s rings. These fringes of equal inclination were first observed by Haidinger and afterwards studied by Lummer and Mascart. From an extended source S, light rays fall on the plate. The rays striking at the same angle form a parallel beam and are viewed through the telescope focused for infinity. The pattern is a series of concentric circles whose centre is the principal focus of the objective of the telescope focused for infinity.
