Wedge Prisms, Laser Beam Steering Prisms, Risley prisms Overview: Wedge prisms also known as Risley prisms are prisms with a small angle between the input and output surfaces. The wedge prisms deflect light toward its thicker portion through a beam deviation ranging from 1° to 10°. For a small angle α between the prism surfaces, the obtained beam deflection angle is approximately (n − 1) α, where n is the refractive index of the prism. For a typical glass prism, where the

Optischer Wollaston-Polarisator Einschichtiges MgF2-Quarz-Wollaston-Prisma

Wollaston Polarizers, Wollaston Prisms, Separating Light Into Linearly Polarized Beams With Orthogonal Polarization Overview: A Wollaston prism separates light into two separate linearly polarized outgoing beams with orthogonal polarization. The two beams will be polarized according to the optical axis of the two right angle prisms. The Wollaston prism consists of two orthogonal prisms of birefringent material—typically a uniaxial material such as Calcite, YVO4 and Crystal

N-SF11 Anamorphotisches Prismenpaar

Anamorphic Prism Pair, Converts Elliptical Beam to Circular Overview: An anamorphic prism pair is used to expand a laser beam in one dimension. This makes it ideal for converting the elliptical beam shape of laser diodes into a nearly circular one. An average throughput of 95% can be achieved if the prism pairs are oriented such that the incident light enters the prism pair at Brewster's angle and each surface has the appropriate AR coating for the wavelength of the incident
