Optical Quartz Windows | High Transparency
Optical quartz window plate is a transparent optical component made of high-purity quartz material, widely used in optical systems, laser technology, semiconductor equipment, aerospace and other fields. Quartz material has excellent optical properties, chemical stability, and thermal stability, making it an ideal material for manufacturing window panels.
Product Features
● High transparency:
Quartz materials have good transparency in the ultraviolet (UV), visible light (VIS), and infrared (IR) bands, especially exhibiting excellent performance in the UV band. The transmission range is usually between 170nm and 2500nm.
● Low thermal expansion coefficient:
Quartz glass has an extremely low coefficient of thermal expansion and can withstand drastic temperature changes without easily deforming or fracturing.
● High chemical stability:
Quartz glass is resistant to acid and alkali corrosion and suitable for use in harsh chemical environments.
● High hardness and wear resistance:
The Mohs hardness of quartz is 7, indicating high mechanical strength and wear resistance.
● High temperature resistance:
The melting point of quartz is as high as 1650 ℃, and it can work stably in high temperature environments.
Application of Optical Quartz Window
Laser technology: used as a window, reflector, or protective mirror for lasers, capable of withstanding the impact of high-energy laser beams.
Optical instruments: used in optical equipment such as microscopes, spectrometers, telescopes, etc., as transparent windows or protective mirrors.
Semiconductor industry: used as a window or mask in lithography machines and wafer processing equipment.
Aerospace: used for high-precision sensors, optical windows, or observation windows, capable of withstanding extreme temperatures and pressures.
UV application: used as a window plate in UV light sources and UV detection equipment due to its high transparency in the UV band.
Medical equipment: used in medical laser devices or optical detection instruments.
