Frequently Asked Questions (FAQ)

Q: What is the specific transmittance of this UV quartz plate in the ultraviolet spectrum?

A: Our high-transmittance transparent quartz plates offer excellent transmission performance in the deep ultraviolet and ultraviolet bands. In the ultraviolet spectral region, transmittance can reach over 80%, while transmittance in the visible light region exceeds 93%. Depending on the application, we also offer materials of different grades, such as JGS1 (far-ultraviolet grade) and JGS2 (ultraviolet grade).

Q: What are the maximum custom sizes for round and square quartz plates?

A: We have proven capabilities for processing large-size components. Round plates can be custom-made up to a maximum diameter of 500 mm, while square plates can reach dimensions of up to 700 mm × 700 mm. Thickness can be flexibly adjusted within the range of 1–100 mm based on requirements. Specific specifications can be precisely cut and polished according to drawings.

Q: Will these quartz plates shatter when used in high-temperature environments?

A: No. These quartz plates have an extremely low coefficient of thermal expansion—1/10 to 1/20 that of ordinary glass—and exhibit excellent thermal stability. Tests have shown that even when heated to 1,100°C and then immediately placed in room-temperature water, they will not shatter, allowing them to withstand various environments with extreme temperature fluctuations with ease.

Q: Aside from high light transmittance, how does this product perform in terms of chemical resistance?

A: Quartz plates are acidic materials with extremely high chemical stability. With the exception of hydrofluoric acid, they react with almost no acidic substances. Their acid resistance is 30 times that of ceramics and 150 times that of stainless steel, enabling them to effectively withstand erosion in corrosive environments.
