Crystals suit high power and UV polarizer applications.

Press Release Summary:



Providing UV transparency and high damage threshold, alpha-BBO Crystals can be fabricated into many optical components such as prisms, optical isolators, and beam displacers. They provide less than 3 arc-min beam deviation, ±0.5° optical axis orientation, and transmission window from 189-3,500 nm. Ranging in size from 70-80 mm x 25-40 mm, chemically stable crystals offer replacement for calcite, YVO4, TiO2, and LiNbO3 components.

CASIX Introduces alpha-BBO Crystals for Precision Optics



Used for high power and UV polarizer applications

Fuzhou, China - February 7, 2006 -CASIX, Inc., a leading manufacturer of high quality crystal and precision optics products, announced the introduction of its alpha-BBO (alpha-BBO) crystals. Because of their unique UV transparency, good mechanical properties, and high damage threshold, alpha-BBO crystals can be fabricated into many kinds of fine optical components such as prisms, optical isolators, beam displacers, and other components requiring high power and a UV polarizer.

CASIX's alpha-BBO crystals have a large birefringent coefficient and wide transmission window range from 189 nanometers to 3500 nanometers. Their high chemical stability, lower inner stress, medium hardness, and UV transparency make them an excellent crystal replacement for calcite, YVO4, TiO2, LiNbO3, and other such components. Compared with natural calcite crystals, whose practical applications are often limited due to their lack of optical homogeneity, small size, and cleavability, alpha-BBO crystals have high optical quality and can reach a size of theta(70~75)x(25~35)mm3.

Specifications for alpha-BBO polarizers:
Surface Quality 20/10 Scratch and Dig
Beam Deviation <3 arc min.
Optical Axis Orientation +/-0.5°
Flatness lambda/4 @ 632.8 nm
Transmission Wavefront Distortion AR-coating R<0.5%
Crystal dimensions:
diameter 70~80mm
length 25~40mm
weight 400~650g
