Supply Optical Quartz Glass Raw Materials JGS1/JGS2/JGS3 block

Optical Quartz  JGS1:JGS2:JGS3 block

The original shape of quartz glass raw materials is cylindrical. Both block and circular quartz glass raw materials are taken from cylindrical quartz raw materials. Whether it is block shaped or circular, it is quartz glass finished product that is convenient for later processing and molding. Generally, quartz discs/plates/windows/lenses and quartz parts in optics are processed from block shaped quartz materials. For quartz parts with high precision requirements, we will use CNC machining to create a frosted shape. Then proceed with precision carving and decoration.

The main characteristics of quartz glass

1. Heat resistance

The softening point of quartz glass is 1730 ℃. It can be used for a long time below 1100 ℃, and the temperature for short time use is up to 1450 ℃.

2. Light transmission

Quartz glass has good light transmittance in the entire optical spectrum from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.

3. Electrical insulation

The electrical resistance of quartz glass is equivalent to 10,000 times that of ordinary glass.

4. Chemical stability

Quartz glass almost don’t react chemically with other acid-base substances except hydrofluoric acid.

5. Thermal stability

Quartz glass has low expansion coefficient, and it can withstand drastic temperature changes.

6. Hardness characteristics

With the hardness of Mohs level 7, the mechanical properties of quartz glass are better than hard glass and ceramics, and the strength of quartz glass improves with the increase of temperature, reaching its maximum when approaching the annealing temperature.
