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 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 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

Optical Lens
We offer Plano-Concave lenses in a variety of materials, including BK7, fused quartz, CaF2, etc., and can be customized to the required size. We also offer a variety of standard sizes and can be coated with anti-reflection films of different wavelengths according to the application. Material selection: BK7 material, suitable for visible to near infrared band, low price, stable performance. Fused Silica material, suitable for deep ultraviolet to near infrared band, low coefficient of thermal expansion, can be used in ultraviolet or high power applications. Coating selection: The single-side reflectance of the material is generally about 4% before the coating, and the single-side reflectance is about 0.25% after the coating.

Double Convex lens is characterized by a longer focal length in the middle of the lens surface and a shorter focal length at the end of each lens surface. They are mainly used to focus light from point sources or to transmit images to other optical systems.
