K9 Drum Lenses are lenses with spherical ends that provide positioning surfaces along the optical axis. They are formed by grinding the outer circle of the spherical lens for easy card mounting and are suitable for the propagation of light in optical communication.
Drum shaped lenses have a shorter focal length and a larger magnification than ordinary convex lenses, and their focal length depends on the refractive index of the material itself. K9 optical glass is an excellent optical material with a wide spectral transmittance. 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 to make them.
Guangtan Intelligent provides drum shaped lenses based on K9 optical glass without coating, with various sizes and focal lengths for you to choose from.
