Prisms are solid glass optics that are ground and polished into geometrical and optically significant shapes. The angle, position, and number of surfaces help define the type and function.
Prism dispersion is dependent upon the geometry of the prism and its index dispersion curve, based on the wavelength and index of refraction of the prism substrate.
Equilateral Prisms - Dispersion
Disperse White Light into Its Component Colors
Right Angle Prisms - Deviation, Displacement
Deviate the Ray Path by 90°
Image is Left-Handed
Used in Combination for Image/Beam Displacement
Anamorphic Prism Pairs - Expansion
Expand Incident Beam Diameter in One Dimension
Ideal for Making Elliptical Beams Circular
Dove Prisms - Rotation
Uncoated: Rotate an Image by Twice the Prism Rotation Angle
Uncoated: Image is Left-Handed
Coated: Reflect Any Beam Entering the Prism Face Back onto Itself
Coated: Image is Right-Handed
