Features
 The prism with the plane surfaces at slight angles(which divert the paths of light through angles by refraction instead of reflection) are called optical wedges. Optical wedges are used in fire control and optial alignment instruments; they may be used where the angle of deviation required is a matter of fractions of seconds. The angle at which a wedge diverts a path of light depends on the angle between the entrance and emergence faces and the index of refraction of the glass.
