Dove Prism

Equilateral Prism

Corner Cubes / Solid Retro Reflectors (CCP):Corner cubes are excellent retro-reflectors. They return an incoming beam in the opposite direction along the same path. They produce a two dimensional 180° beam deviation making them useful for alignment purposes. These prisms are manufactured from BK7A or Fused Silica and may be selected to have 2, 5 or 10 arc sec angular deviation tolerance. The prisms are supplied uncoated but Lambda can apply anti-reflection coatings to the entrance face and protected metallic coatings to the three cube corner faces as required.
Dove Prisms (DVP):Dove prisms are routinely used to invert images or as optical delay lines. They are supplied uncoated but a variety of coating options are available. UV Fused Silica prisms are recommended for high power applications.
Equilateral Prisms (EQP):Equilateral prisms are normally used as dispersing prisms. As well as standard BK7 prisms, higher index. SF2 and F2 prisms are offered to increase the dispersive power.
Isosceles Brewster Prisms (IBP):Brewster Prisms are isosceles prisms arranged to have an apex angle which permits a ray entering at the Brewster angle to pass at minimum deviation. They are ideal for selection of wavelengths or tuning of laser output. If required for use with femto-second lasers please contact us and ask for the ultra-fast version.
Littrow Dispersing Prisms (LDP):Littrow prisms are retro-reflecting Brewster prisms. They are arranged to that a beam entering at the Brewster angle falls normal to the flat surface and is reflected back along the same path. They are useful in laser cavities where the wavelength of the return beam can be selected by tilting the prism slightly. In this way the gain of the cavity can be tuned to a specific laser line.
Pellin Broca Prisms (PBP):Pellin Broca prisms are constant deviation (90°) dispersing prisms. The input angle is arranged so that total internal reflection occurs at the internal face. This will provide a constant 90° deflection for the beam with dispersion. If the input beam enters the long side of the prism the longer wavelengths will be deviated less. These prisms provide a convenient way to compensate for group velocity dispersion in ultra-fast lasers or to separate harmonic wavelengths in an incoming laser beam.
Penta Prisms (PTP):Penta prisms are extremely useful in alignment systems as they define a right angle very precisely and independently of angle of incidence. Rays entering one face emerge from the adjacent face at precisely 90° after they have undergone two reflections inside the prism for a total of 270°. The penta prism acts as a turning mirror which is insensitive to alignment. For custom applications, anti-reflection coatings are applied to the entrance & exit surfaces. Either metallic or dielectric high reflector coatings are applied to the 2 reflective surfaces.
Porro Prisms (PRP):Porro prisms are sections of a right angle prism. They are specifically intended for 180° folding. These Porro prisms are circular in cross section and have a λ / 10 polished input face. An incoming beam is totally internally reflected at the roof faces and returned in the opposite direction within 10 arc sec.
Rhombic Prisms (RP):Rhombic prisms are used to displace a beam laterally without changing its direction. They may be coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. These prisms are manufactured from either BK7A or Fused Silica. They are supplied uncoated but many coating options are available.
