Precision Glass and Optics Right Angle Prisms
Commonly used to create a 90° bend in the light path, these prisms present images two ways depending on their orientation. In the first, images will be inverted but positioned correctly left to right. Rotate the prism 90°, and images will be right side up, but transposed horizontally. Several right angle prisms can be combined to ...

Penta Prism / Half Penta Prism
The penta prism employs reflection off two surfaces to deviate a light beam by 90° while preserving image parity. The beam deviation is invariant to slight rotation of the prism, making it useful for applications where critical alignment is necessary. Alternate prism configurations include the roof penta, which reverses the parity of ...

Littrow Prisms are of the same design as Brewster prisms but cut in half vertically from the apex to the base. They are normally used in a laser cavity or prism spectrometer to select a particular wavelength. In general, the beam is incident on the hypotenuse and is reflected back from the rear surface. It exits from the hypotenuse ...

SF10 Brewster Prism
Brewster Prisms are designed to have an apex angle such that a p-polarized ray incident at Brewster’s angle will pass through the prism parallel to the base at minimum deviation, and exit also at Brewster’s angle. In this case surface reflection losses are negligible. Brewster Prisms are often used in situations where surface ...

Penta Prism 20 - 20 mm
Penta Prisms deviate an incident beam through 90° without inverting or reversing it. They also show constant deviation (i.e. the beam is deviated through 90° irrespective of the orientation of the prism). The accuracy of the 90° deviation is therefore only dependent on the manufacturing tolerances of the prism. These ...
