When we talk about optical glass, it must involve UV glass. Special fused silica glass is an excellent UV-transmissive material. Due to different usage scenarios, UV fused silica glass is divided into different optical properties JGS1/JGS2/JGS3. Although divided into different optical properties, the main content is still SiO2 (more than four nines). Our company offers three quartz glass materials with different optical properties. JGS1 (synthetic quartz/quartz glass) is mainly used in the field of far ultraviolet optics, JGS2 (fused silica glass) is used in the field of general optics, such as quartz glass windows, quartz plates, quartz glass parts, JGS3 (far infrared) quartz glass) is used in Microwave and other far-infrared fields. So how to achieve this distinction of optical properties? A simple generalization is determined by the trace elements inside the quartz glass material. The optical properties of quartz glass can be changed by adding different trace elements. Sometimes you can even change its physical properties, like colored quartz glass.
