WOLLASTONE POLARIZER

We can provide Wollaston prisms in a variety of materials, including Calcite crystals, A-BBO crystals, quartz crystals, YVO4 crystals, etc. Wollaston prism is made of two crystals bonded or photoadhesive, which can change the incident unpolarized light into two orthogonal polarized light beams. It can work in a wide band range, and the field of view is relatively large. Unlike other polarizers, both of Wollaston's output beams are highly polarized, with extinction ratios greater than 10,000:1 or 100,000:1. The beam separation Angle can be customized according to customer requirements, and the beam splitting output can be achieved at any Angle from 0 to 25°. The material of the prism can be selected according to the size of the beam splitting Angle and the band used.

YVO4

Yttrium alumate (YVO4) is an excellent birefringent crystal material, which is a negative uniaxial crystal. The crystal has good physical and mechanical properties, wide light transmission range, high transmittance, large birefringence coefficient and easy processing. YVO4 crystal can replace ice SPAR and crystal red stone in the field of optical fiber communication, is the key material in optical communication passive devices such as optical isolators, circulators, polarization splitters, polarizers.


Caicite

Caicite Crystal is a kind of natural birefringent material, in the shape of diamond, birefringence coefficient is large, through the spectrum is wide, from visible to near infrared has relatively good optical properties. Although the mechanical strength of Iceland SPAR material is soft and easy to scratch, it still does not affect its wide application in polarization devices. Caicite is mainly used in Glan POLARIZER.


LiNbO3

LiNbO3 is widely used in optical fiber communication as a birefringent crystal. The crystal has good physical and mechanical properties, wide light transmission range, high transmittance, easy processing, and lower material cost than other materials. Lithium niobate crystals are widely used in passive optical communication devices such as optical isolators, circulators, polarization splitters, polarizers, etc


POLARIZING BEAM SPLITTER(PBS)

The polarization splitter prism is plated with a multilayer film structure on the inclined surface of the right Angle prism, and then glued into a cube structure. By taking advantage of the property that the transmission rate of P-polarized light is 1 and that of S-polarized light is less than 1 when the light incident at Brewster Angle, the P polarization component can be completely penetrated after the light passes through the multilayer film structure at Brewster Angle for many times. And most of the S polarization component is reflected. Note: Specific bands and extinction ratios can be customized according to customer requirements.
