1. Fused silica Glass (JGS1/JGS2/JGS3)
Superior UV transmittance (>80% @185-250nm for JGS1)
Broad spectral range: 185-3500nm (JGS1/JGS2 for UV; JGS3 for IR)
Extremely low thermal expansion coefficient (5.5×10⁻⁷/℃)
2. UV-Transmitting Black Glass (Wood's Glass)
Opaque to visible light (400-700nm) with >85% UV transmittance (300-400nm)
Contains metal oxide dopants for bandgap engineering
3. Soda-Lime Silicate Shortwave UV Glass
Optimized for 254nm Hg lamp emission (transmittance >75%)
Cost-effective alternative to quartz (1/5 the price)
Chemically strengthened to 800MPa mechanical strength
