Quartz Windows are high-purity fused silica glass optical windows, widely used in laser systems, semiconductor equipment, optical instruments, and high-temperature industrial observation windows.
The JGS series includes JGS1, JGS2, and JGS3, each optimized for deep ultraviolet (DUV), standard ultraviolet (UV), and infrared (IR) applications, offering:
-
High optical transmission: 185 nm to 3.5 μm, visible light transmittance over 90%
-
Excellent thermal stability: short-term up to 1300°C, long-term stable at 1100°C
-
Superior chemical resistance: resistant to most acids and alkaline solutions
-
High mechanical strength: density 2.2 g/cm³, compressive strength 1100 MPa, Mohs hardness 6–7
