**Dispersive Prism**

**Features**

Equilateral dispersing prisms are used for wavelength separation applications. The three sides are of equal length. A light ray is twice refracted passing through the prism with total deviation denoted by qd in the figure below. Deviation is a function of refractive index, and hence wavelength. Angular dispersion Dqd is the difference in deviation for light rays having different wavelengths and varies with prism orientation.

**Penta Prism**

**Features**

The penta prism is a five-sided prism. It reflects light rays through a 90° angle by two reflections and does invert or revert the image. The reflecting surfaces are aluminized. Slight movement of the prism does not affect the true right angle at which light rays are reflected. It also shortens the optical path length of an instrument.
