Quartz glass is widely used in many optical device fields.

Our quartz glass plates have high purity, low hydroxyl, low bubble properties and excellent 

transmittance at 260-2500 nm. Through our advanced welding technology, we can produce 

quartz sheets up to 1500mm in length, suitable for use as components of optical instruments, 

quartz glass instruments for the semiconductor industry, etc.

Quartz glass can also be used to make convex lenses for large astrotelescopes. A single piece 

is 3.8m in diameter and 50mm thick.

So many optical devices that require good UV penetration use mirrors, lenses, and small Windows 

are made of quartz glass.

With the advancement of science and technology and the improvement of industrial level of 

our country, the application of quartz glass has been integrated into People's Daily life. In the 

field of new energy, quartz glass is used in the "Shenguang-III" host device developed by our 

country, as an important material of terminal optical components such as vacuum window, lens, 

shield plate, polaroid plate, continuous phase plate, beam sampling grating and so on. In the field 

of microoptical materials, quartz glass materials are widely used in the microlens industry because 

of their excellent transmission ratio in the ultraviolet to infrared continuous wavelength range. Microlenses 

are commonly used in digital cameras, computer display screens, CCD camera lenses and medical instruments.

Mirror is one of the important parts of space optical system such as space telescope, exploration 

satellite, weather satellite and reconnaissance satellite. With the development of space imaging 

technology and the deepening of human cognition of the universe, people's requirements on the 

precision of space optical system are also improved. The mirror surface should not only have high 

resolution, but also have good imaging quality. Space is a gravity free environment with a large 

temperature difference. In addition, the load requirements for launching optical systems into space 

should be taken into account. At the same time, the production of large-size optical systems in space 

requires materials with small thermal deformation coefficient, large specific stiffness and small surface 

roughness.

Low expansion quartz glass has very low coefficient of thermal expansion, and good cold and hot processing performance, can be made into closed honeycomb structure. The preparation technology of low expansion quartz glass material is relatively mature, and it is widely used in optical engineering, such as the primary mirror blank of Hubble Space telescope.

As a special optical material, quartz glass plays an extremely important role in the field of aerospace, semiconductor and precision devices. Its performance directly restricts the resolution, accuracy, stability and reliability of related equipment.
