Optical quartz glass has the characteristics of high temperature resistance, corrosion resistance, and low expansion rate, and is widely used in the optical field. High-purity quartz glass is used in the production of telescope lenses and laboratory optical equipment, communication equipment, diffractive lenses, projection displays, scanning equipment and Optics for printers, lasers, and cameras and ultra-flat TV screens, flame control equipment, and more.
A high-power laser driver is a necessary device for carrying out high-energy density physics and laser confinement fusion experiments. The core unit is the terminal optical component, which undertakes functions such as frequency conversion, focusing, and harmonic separation. The terminal optical component requires a variety of Quartz components, including various lenses, beam sampling gratings, continuous phase plates, etc.
Electric light source glass can be divided into potassium-calcium glass, lead-containing silicon glass, borosilicate glass, aluminum-silicate glass and quartz glass according to the chemical composition. The electric light source products produced with high-purity quartz glass include high-pressure mercury lamps, metal Halide lamps, halogen dock lamps, xenon-based lamps, automotive lamps, etc., can withstand high temperatures and provide high transmission characteristics.
In order to ensure the quality of the quartz glass tube, it is necessary to reduce the number of hydroxyl groups and the impurity content in the raw materials, especially the alkali metal ions in the raw materials, because the hydroxyl groups and alkali metal ions will reduce the thermal performance of the glass, and every increase of 1×10-5 hydroxyl content, will reduce the use temperature by about 0.5°C.
For compact fluorescent lamp CFL and cold cathode fluorescent lamp CCFL, mercury is used as the lighting medium. Sodium oxide will react with mercury to form mercury amalgam. Too much mercury consumption will reduce the service life. Therefore, the content of sodium oxide in raw materials needs to be reduced. The current research and development trend is low-sodium lead-free glass, which is a material for green lighting and is conducive to environmental protection.
