Synthetic Fused Silica vs. Natural Quartz Filter Substrates
Material selection determines overall optical lifetime. Choosing between high-purity JGS1 (Synthetic UV Fused Silica), JGS2 (Optical Grade Fused Quartz), and JGS3 (Infrared Grade Quartz) depends entirely on spectrum band requirements and OH⁻ radical absorption bands.

|---|---|---|---|---|---|
| JGS1 Synthetic Silica | 185 nm – 2,500 nm | < 1,200 ppm (High OH) | λ/10 @ 632.8 nm | 10-5 to 20-10 Scratch-Dig | DUV Excimer Optics, HPLC Detectors, Lithography Viewports |
| JGS2 Optical Quartz | 220 nm – 2,500 nm | < 30 ppm | λ/4 @ 632.8 nm | 40-20 to 60-40 Scratch-Dig | Sight Windows, Industrial UV Curing Filters, Furnace Plates |
| JGS3 Infrared Silica | 260 nm – 3,500 nm | < 5 ppm (Water-free) | λ/8 @ 632.8 nm | 20-10 Scratch-Dig | Infrared Pyrometry, Mid-IR Gas Sensing, Laser Thermal Windows |
| Cerium / Samarium Doped | Selective Cut-off / Absorption | Variable | λ/4 @ 632.8 nm | 40-20 Scratch-Dig | IPL Flow Plates, Nd:YAG Laser Cavity Shrouds (1064nm filter) |
| Precision Borofloat 33® | 350 nm – 2,500 nm | Standard Silicate | λ/2 @ 632.8 nm | 60-40 Scratch-Dig | Cost-effective Viewports, Biological Substrates, Microfluidic Caps |

Frequently Asked Technical Questions (FAQ)
Practical answers to common material, tolerance, and process questions from optical procurement and mechanical design teams.
High hydroxyl content ([OH⁻] ~1200 ppm, e.g., JGS1) prevents color-center formation under high-energy Deep UV photons, making it ideal for excimer lasers and UV spectroscopy. However, in infrared regions, high OH creates strong absorption dips at 1.4 µm, 2.2 µm, and especially 2.73 µm. For Mid-IR viewports, low-OH synthetic silica or water-free JGS3 quartz ([OH⁻] < 5 ppm) is required for broad transmission up to 3.5 µm.
Fused quartz features an extremely low coefficient of thermal expansion (CTE ~5.5 × 10⁻⁷ /°C from 20°C to 320°C). This allows properly annealed quartz plates to survive rapid quenching from 1100°C into ambient-temperature water without catastrophic fracture. However, uneven mechanical clamping or unchamfered edge microcracks can create localized stress risers, reducing effective shock thresholds.
We accept STEP, IGES, DWG, DXF, and dimensioned PDFs. Key parameters include operating wavelength, permissible scratch-dig levels (e.g., 20-10 for laser-grade vs. 60-40 for viewports), surface flatness (λ/4 to λ/10), clear aperture limits, edge bevel specifications, and working temperatures.
Devitrification (transformation from amorphous silica to crystalline cristobalite) occurs above 1000°C, typically accelerated by surface alkaline contamination (Na⁺, K⁺, Ca²⁺, finger grease). We use high-purity ultrasonic hydrofluoric acid etching, cleanroom DI water rinsing, and high-temp vacuum annealing to keep plates clean, preventing premature surface haze and crystallization during operation.
