Prisms we manufacture

Dispersive prisms are used to break up light into its different spectral colors because the refractive index depends on frequency; the white light entering the prism is a mixture of different frequencies, each of which gets bent slightly differently. Blue light is slowed down more than red light and will therefore be bent more than red light.

We manufacture the following types of prisms:

Triangular prism
Abbe prism
Amici prism

Reflective prisms

Reflective prisms are used to reflect light, in order to flip, invert, rotate, deviate or displace the light beam. They are typically used to erect the image in binoculars or single-lens reflex cameras – without the prisms the image would be upside down for the user. Many reflective prisms use total internal reflection to achieve high reflection.

We manufacture the following reflective prisms:

Porro prism
Porro–Abbe prism
Amici  prism
Pentaprism
Schmidt–Pechan prism
Dove prism
Retroreflector prism

Beam-splitting prisms

Deflecting prisms

Wedge prisms are used to deflect a beam of light by a fixed angle. A pair of such prisms can be used for beam steering; by rotating the prisms the beam can be deflected into any desired angle.
