Nantong Yinxing Optical Co., Ltd. specializes in the production and processing of optical glass (including filters) and special glass, offering a variety of products such as colored optical filters, clear optical filters, coated optical filters, and other specifications of optical glass.

Borosilicate glass utilizes the conductivity of glass at high temperatures to achieve melting through internal heating within the glass, and is processed using advanced production techniques. It is a colorless and transparent glass with an extremely low thermal expansion coefficient, resistant to high temperatures and capable of withstanding rapid temperature changes of up to 200 degrees. It transmits wavelengths between 300nm and 2500nm with a transmittance of ≧90% and a thermal expansion coefficient of 3.3. It is resistant to both acids and alkalis, withstanding temperatures around 400°C, and can reach approximately 550°C after special treatment. Borosilicate glass is one of the better heat-resistant instrument glasses, widely used in various heat-resistant glass instruments, such as chemical corrosion-resistant equipment and piping, laboratory glassware, and also serves as excellent glass for lampworking.
