Optical quartz glass

Optical quartz glass is an amorphous material with high-purity quartz (SiO2) as the main component. It is widely used in many high-tech fields due to its excellent optical and physical properties. The following is an introduction to some of the main features and application areas of optical quartz glass:

Main features
High transmittance: Optical quartz glass has extremely high transmittance in the ultraviolet, visible and near-infrared ranges, especially in the ultraviolet region (200-300 nm), its transmittance can reach more than 90%.

Low thermal expansion coefficient: Optical quartz glass has an extremely low thermal expansion coefficient, which allows it to maintain dimensional stability when the temperature changes and is not prone to thermal stress.

High heat resistance: This material can withstand temperatures of up to 1000 degrees Celsius and still maintain excellent optical properties at high temperatures.

Excellent chemical stability: Quartz glass has strong corrosion resistance to most chemical reagents (such as acids, alkalis, and salts), especially under high temperature conditions, its chemical stability is particularly outstanding.

High mechanical strength: Although quartz glass is a brittle material, it has a high hardness and relatively large compressive strength.

Application fields
Optical components: Due to its high transmittance and excellent optical properties, optical quartz glass is often used to manufacture various optical components, such as lenses, prisms, optical fibers, window materials and filters.
Semiconductor industry: In the semiconductor manufacturing process, optical quartz glass is used as a mask, crucible, observation window and various substrate materials for photolithography.
Laser technology: Quartz glass is used to manufacture optical components in laser cavities and laser amplifiers, as well as window materials for laser devices.
Ultraviolet light source: Due to its high transmittance in the ultraviolet region, quartz glass is widely used in ultraviolet lamps, ultraviolet lasers and other ultraviolet light source equipment.
Aerospace: In the field of aerospace, optical quartz glass is used to manufacture windows for high-precision optical instruments, astronomical observation equipment and protective covers for various sensors.
Scientific research: Optical quartz glass is widely used in spectroscopy, optical experiments and high-energy physics research, especially in optical experiments that require high transmittance and low loss.
