Product Name Notes
Excellent for Severe Environments High Chemical Stability Sapphire and Ruby half-ball (hemispherical) lenses feature a very short back focal length with the convenience of a flat surface for easy mounting.
Excellent for Severe Environments High Strength and Hardness High Chemical Stability Sapphire and Ruby ball lenses are both made from AL203. Ruby or Ruby-Doped sapphire owes...
Excellent UV Transmission Low Coefficient of Thermal Expansion Ball and Half-Ball Options Available Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making...
Fiber Coupling Half-Spheres Collimating Lenses Half-ball (hemispherical) lenses are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.
High Index for a Closer Focal Distance High Tolerance The use of high index glass results in a decrease of the back focal length. Shorter distances simplify fiber coupling. This...
Index of Refraction of 2.0 High Tolerance These ball lenses have an even higher index of refraction than our LaSFN9 ball lenses, providing a shorter back focal length, which simplifies...
Useful as Fiber Coupling Spheres and Collimating Lenses Standard and High Tolerance Options Available for N-BK7 Substrate Ball lenses are glass spheres commonly used in fiber optic applications. They are...
