High-Precision Engineered Substrates
Immediate capacity allocations for customized rectangular optical blanks, laser flow assemblies, and semiconductor carriers fabricated to drawing.
Technical Architecture of Synthetic vs. Fused Silica Plates
Understanding material differentiation across JGS1, JGS2, and JGS3 synthetic matrices dictates long-term performance under thermal shock, ionizing radiation, and deep UV illumination.
JGS1 Synthetic UV Grade
Manufactured via high-purity chemical vapor deposition (SiCl₄), JGS1 exhibits virtually zero bubble inclusion and trace metallic impurities below 1 ppm. Optimized for excimer laser optics, lithography masks, and deep UV spectrometers down to 185 nm.
JGS2 Fused Natural Quartz
Smelted from select high-grade natural quartz crystals under an oxyhydrogen flame. Offers an exceptional balance of mechanical rigidity, broad visible-to-infrared transmission, and thermal stability up to 1,100 °C continuous service.
JGS3 Low-OH Infrared Grade
Treated by vacuum electro-fusion to strip internal hydroxyl groups (OH content < 2 ppm). Completely eradicates the classic water-absorption dip at 2,730 nm, unlocking pure transmission across thermal imaging and MWIR broadband laser optics.
