Details

UV fused silica Ball Lenses are used to improve the signal coupling between optical fibers, transmitters and detectors, improve the signal quality, and can also be used in endoscopes, bar code scanning, aspheric lens pre processing materials, sensors, etc.
Due to the short focal length of the spherical lens, it can greatly reduce the distance required from the spherical lens to the optical fiber, so spherical lenses are mainly used in optical fiber applications. UV fused silica glass has a wider spectral range (185nm-2.1 μ m) than K9 optical glass, and has excellent transmittance in the UV band. It has lower refractive index, better uniformity, smaller thermal expansion coefficient, and higher chemical resistance and low fluorescence. It can be used to make various optical elements.
The optical probe intelligence provides a spherical lens whose substrate is ultraviolet fused silica without coating. There are a variety of sizes and focal lengths for you to choose from.
