JGS1 Technical Specifications:
- High Purity: OH content < 1200 ppm, providing superior radiation resistance.
- Optical Quality: Bubble-free (Class 0), Stress birefringence < 5nm/cm.
- Applications: Deep UV laser windows, semiconductor lithography, and high-precision spectroscopy.
2. Expertise & Custom Fabrication Capabilities
- JGS Fused Silica Mastery: Our JGS1 Fused Silica components are manufactured via Chemical Vapor Deposition (CVD), ensuring ultra-high purity with OH content below 1200ppm. It is the ideal alternative for Heraeus Suprasil in high-power laser windows and deep UV spectroscopy. We offer precision surface finishing (S/D 10/5) and custom AR/AF coatings for drone and industrial applications.
- 0.21mm Ultra-Thin Precision: Specialized cutting and finishing for D263T and B270 glass, ideal for advanced sensor integration.
- Optical Coatings: In-house AR (Anti-Reflective) and HR (High-Reflection) coating to optimize transmission or reflectivity for specific wavelengths.
- Certified Cleanroom Facility: All components are fabricated, cleaned, and inspected in our ISO-certified cleanroom environment to ensure zero-defect quality.
