K9 Double Concave (DCV) lenses are double concave lenses made of K9 glass as the base material.
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, such as lenses, window plates, filters, spectrometers, reflectors, prisms, etc. It will diverge the light and has a negative focal length, consisting of two concave surfaces with equal curvature. It is commonly used for beam expansion, projection, and enlarging the focal length of optical systems in lenses.
The K9 dual concave lens of Guangtan Intelligent has lenses of various sizes and focal lengths, providing coated and uncoated products. The broadband anti reflective film can be used in the VIS (visible light) band, NIR (near-infrared) band, and SWIR (short wave near-infrared) band to meet various applications in different scenarios and bands. Guangtan Intelligent can also customize lenses of other specifications according to your actual needs.
