Optical glass can change the direction of light, as well as relative spectral distribution of ultraviolet, visible or infrared light.Optical glass material is the most common type because of its excellent optical properties such as high light transmission and environmental stability.
Nd-Vd diagram of Optical Glass
UNI-Optics has capability in manufacturing various optical components with a wide variety of optical materials.Selecting optical material is very important since each material has different optical characteristics, such as transmission versus wavelength, index of refraction, thermal, mechanical and chemical characteristics.You may need specific information when selecting the material for a custom component. The data in the following is intended to assist in these situations The simplest
way to select the right materials is to let UNI Optics know yourapplications, and our engineers would like to help you to select the right material from Chinese glass.
