Photonchinas beamsplitters are used to split or combine beams of light. Plates are used for most laser applications as they exhibit low absorption. Cubes are a convenient, protected form for low power applications. The performance of a beamsplitter is mainly dependent on the coating specifications. Non-polarizing beamsplitter (high power NPBS) is a kind of special polarizing beamsplitter. It makes the p-polarization component and S- polarization component of incident light have similar spectral characteristics.
Photonchinas wollaston polarizer can separate an incident beam into two rays: extraordinary and ordinary ray with a deviation angle which is dependent on wavelength. Both rays are transmitted through the other surface. Specifications: Material: a-BBO, Calcite ,YVO4,Quartz Wavelength Range: a-BBO:190-3500 nm, Calcite:350-2300 nm, YVO4:400-5000 nm,Quartz:200-2300 nm Extinction Ratio: Calcite,Quartz:

Photonchina has been focusing on dove prism manufacture for more than decades in order to meet demands of customers worldwide in applications ranging from image displaying to fiber communications. Dove prism is a type of reflective prism which is used to invert an image. These prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense. If you look through the prism and rotate it around a longitudinal axis, the image rotates through twice the angle through which the dove prism itself rotates. For optimal performance, you may use dove prisms with collimated light. The top surface of each dove prism is ground and the longest length features an unbeveled sharp edge. Dove Prisms are offered uncoated, with anti-reflection coated diagonal faces, or with aluminized diagonal faces. Aluminized dove prisms feature a protected aluminum coating with black Krylon paint on the diagonal faces and are ideal for displaced retroreflection. They provide a u-turn for incident laser beam light.
Achromatic Waveplate Achromatic waveplate is made from two different substrate materials such as crystal quartz and magnesium fluoride. For the single material,waveplateâ??s working wavelength is very limited because of the dispersion of the material. But Achromatic Waveplate uses two different kinds of materials,with the different dispersion, such waveplate is not sensitive to the wavelength change. Dual Wavelength Waveplate Dual wavelength waveplate is a special type of multiple waveplate that provides a specific retardance at two different wavelengths, itâ??s particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength. It is widely used to improve conversion efficiency in solid double frequency laser device. Polarization Rotator Due to the rotation activity of natural quartz crystal, it also can be used as polarization rotators so that the plane of input linearly polarized beam will be rotated at special angle which is determined by the thickness of quartz crystal.
Wavepalte Types: Photonchinas waveplates include octadic waveplate (1/8 waveplate),quarter waveplates(1/4 waveplate), half wave plates(1/2 waveplate) and full waveplate Both circular aperture and quadratic aperture are available. Photonchinaâ??s waveplate can transmit light and modify its polarization state without attenuating, deviating, or displacing the beam.It is ideal for applications requiring high damage thresholds and retardation stability over temperature change, such as for use with lasers or infrared light sources.
