Details

K9 spherical lens is an optical glass bead made of K9 material, used to improve the signal coupling between optical fibers, transmitters, and detectors, enhance signal quality, and can also be applied to endoscopy, barcode scanning, pre-processing materials for non spherical lenses, 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. K9 optical glass is an excellent optical material with wide spectral transmission. It has high transmittance from 350nm to 2000nm, high hardness, and can withstand various physical and chemical stimuli. It has low content of bubbles and impurities, so it is often used as a substrate for various optical components.
Guangtan Intelligent provides spherical lenses based on K9 optical glass without coating, with various sizes and focal lengths for you to choose from.
