The 5-500mm transparent polished quartz plate is a high-purity, high-light-transmittance optical grade quartz glass plate that has been precision polished for excellent surface flatness and optical properties. The product is made of high-purity fused silica (SiO ⊃2;), with an extremely low coefficient of thermal expansion, excellent high temperature resistance (up to 1200 ° C), and excellent ultraviolet-infrared light transmission (light transmittance > 90%), suitable for harsh optical, semiconductor, laser and scientific research experimental environments.

FAQ

Q1: What is the light transmission range of this transparent polished quartz plate?

A1: Our quartz plate has excellent transmittance in the ultraviolet to near-infrared band (usually 190nm-2500nm), especially without obvious absorption peaks in the ultraviolet region, making it very suitable for precision optical detection and spectral analysis applications.

Q2: What sizes and thicknesses does the product support customization?

A2: Fully supported. We provide customized services for diameters or side lengths ranging from 5mm to 500mm, and the thickness can also be processed according to the drawings. Both standard sized window panels and special specification optical components can be produced on demand.

Q3: What level of polishing accuracy can be achieved on the surface of quartz plates?

A3: We offer multiple polishing grades, with surface roughness (Ra) controllable at extremely low levels (such as Ra<0.1 μ m), ensuring compliance with the stringent requirements of high-precision laser systems, semiconductor lithography, and precision optical instruments.

Q4: Is this material resistant to high temperatures and corrosion?

A4: Yes. Quartz plates have an extremely low coefficient of thermal expansion and can withstand drastic temperature changes without breaking. At the same time, it has strong corrosion resistance to almost all acids and chemical solvents except hydrofluoric acid and hot phosphoric acid.
