Daheng Optics GCL-06/07 Crystal componentsCrystal Components Polarized light Polarized light has the optical radiation with its electric field vibrating in a specific regular mode. Any generally polarized electric field can be resolved into two orthogonally polarized components. If the light is plane polarized, the electric field vibrates in a single plane - the plane of polarization, and the two components are in phase. If it is elliptically polarized, the two components have a constant phase difference, and the tip of the electric field vector follows a three dimensional ellipse as the beam...

GCL-06/07 Crystal components Crystal Components Birefringent Materials We use two principal materials out of a fairly wide range of birefringent crystals for the production of our polarizing components, calcite and crystal quartz. Calcite is a widely preferred choice of material owing to its very high birefringence, wide spectral transmission and the availability of reasonably sized rhombs. It has the advantage of being non-hygroscopic, so that protection from the atmosphere is not necessary, though it is a fairly soft crystal and is easily scratched. Quartz is another extremely useful birefringent...

Daheng Optics Crystal Components under the two refractive indices. On exiting the plate, the two components recombine with a different phase relationship to the input beam, dependent on the plate thickness. The most useful retardations are a quarter and half wavelength for polarization analysis and separation purposes. A quarter waveplate introduces a 90 degree phase shift between the two components, producing circularly polarized light. The sign of the phase shift determines whether the beam is left or right circularly polarized. A half wave plate introduces a 180 degree phase shift, which has...

GCL-06/07 Crystal components GCL-0604 Quartz Zero-Order Waveplates Crystalline quartz is frequently used for the stringest quality retardation applications. Zero-order waveplate is made by cementing two quartz plates with their fast axes orthogonal to each other. The difference in thickness is equal to either A/4 or A/2 for a specified wavelength. Compared with multiple-order quartz retarders, they are much more insensitive to wavelength, temperature and angle of incidence. Waveplates of other wavelength and sizes are avalible for custom made. • Material: • Diameter: •Thickness: • Retardation...

It is one of the most common types of modern polarizing prism. It was first described by Archard and Taylor in 1948. The prism is made of two right-angled prisms of calcite (or sometimes other birefringent materials) which are separated on their long faces with an air gap. The optical axes of the calcite crystals are aligned parallel to the plane of reflection. Total internal...

Daheng Optics GCL-06/07 Crystal components GCL-0711 Wollaston Prisms A Wollaston prism, invented by William Hyde Wollaston, is an optical device that manipulates polarized light. It separates randomly polarized or nonpolarized light into two orthogonal linearly polarized outgoing beams. The Wollaston prism consists of two orthogonal calcite prisms, cemented together on their base to form two right triangle prisms with perpendicular optic axes. The Wollaston prism is commonly used as a polarizing beamsplitter. The deviations of the two transmitted beams are nearly symmetric about the incident...
