Equilateral Prism SF10 60mm
Equilateral Prisms are used routinely as dispersing elements where spectral separation is required. They provide better brightness (lower stray light) than diffraction gratings. They also have greater power handling capabilities and avoid possible confusion when trying to interpret overlapping spectral orders. It must be remembered ...

Glass Laser Quality Right Angle Prism 25.4mm
A Right Angle Prism is used to turn or deflect a beam through 90° or 180°. In either case this is achieved by total internal reflection and produces a very efficient broadband reflector. It is important that the incoming beam is collimated and enters the prism at a normal angle of incidence. This is so that total internal ...

12.7mm Littrow 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 ...

Dove Prisms 400-700 nm
Dove Prisms are a truncated form of right angle prism. They use total internal reflection to produce an inverted image which emerges without any beam deviation. The main application for these prisms are as image rotators. Rotating the prism about an optical axis results in the image rotating at double the angular velocity of the ...

Penta Prisms 400-700 nm
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 prisms are ...

Anamorphic Prism Pair 650-850 nm
Anamorphic Prism Pairs are used mainly to correct the asymmetric beam shape of a Laser Diode – from elliptical to near circular shape. This is done by expanding (or contracting) the beam in one direction only while the other direction remains unchanged. The aspect ratio of the elliptical beam varies according to the laser ...

Porro Prism
Porro prism is a type of reflection prism which can be used to alter the orientation of an image. Light enters the large face of the prism, then hits on the roof, by total internal reflection twice from the roof, the beam exits again through the large face. An image traveling through a Porro prism is rotated by 180deg but not inverted.

Half Penta Prism
Half-Penta prisms or Semipentaprisms are used to deviate the line of sight by 45° without inverting or reverting the image. The beam is reflected twice in the prism, with one reflection happening at less than the critical angle, therefore the prism requires aluminized and over-coated with Inconel and black paint for ...
