JGS1 JGS2 Optical Quartz Glass Protective Lenses For Laser System
Material:
• JGS1 Quartz Glass: Made from synthetic stone with SiCl4 as raw material, melted by high-purity oxyhydrogen flame. Contains a high amount of hydroxyl (around 2000 ppm).
• JGS2 Quartz Glass: Produced by gas refining with crystal as raw material, containing metal impurities in the range of dozens of PPM.
Properties:
• JGS1:
• Excellent UV transmission, especially in the short-wave UV region.
• High transmission rate at 185 nm, reaching 90% or more.
• Practically free of bubbles and inclusions.
• JGS2:
• Good UV and visible transmission.
• Contains absorption peaks at 2730 nm due to hydroxyl content (100-200 ppm).
• May have bubbles in larger dimensions.
Function:
• Protection: Shields sensitive components in laser systems from environmental damage and contamination.
• Transmission: Ensures high transmission of UV and visible light, crucial for laser efficiency.
• Durability: Resistant to high temperatures and pressures, maintaining performance under extreme conditions.
Application:
• Laser Systems: Used as protective windows and lenses to safeguard laser components while allowing optimal light transmission.
• Optical Instruments: Employed in microscopes, telescopes, and other devices requiring precise light manipulation.
• High-Temperature Devices: Suitable for use in environments with high thermal and mechanical stress.
• Scientific Research: Utilized in experiments requiring high UV transmission and minimal optical distortion.
Summary:
JGS1 and JGS2 optical quartz glass protective lenses are essential for laser systems and other high-precision optical applications. JGS1, with its superior UV transmission and minimal inclusions, is ideal for deep UV and visible wavelength operations. JGS2, while slightly less pure, offers good UV and visible transmission and is suitable for a broader range of applications. Both materials are highly durable, capable of withstanding high temperatures and pressures, making them invaluable in protecting sensitive optical components. Their unique properties ensure that they provide excellent protection and transmission, enhancing the performance and longevity of laser systems and other optical devices
