When selecting the right quartz glass for precision optical components—especially for drone cameras, laser systems, or industrial sensors—understanding the differences between JGS1, JGS2, and JGS3 is critical for both performance and cost-efficiency.
While all three are high-quality silica materials, their manufacturing processes and transmission ranges vary significantly.
| Property | JGS1 (Transparent Synthetic) | JGS2 (Quartz Glass) | JGS3 (Infrared Quartz) |
| Material Origin | Synthetic Chemical (SiCl4) | High-quality Natural Quartz | Natural/Synthetic (Low OH) |
| Main Transmission | Deep UV + Visible | UV + Visible + Near-IR | Visible + Infrared (IR) |
| Spectral Range | 185nm – 2500nm | 220nm – 2500nm | 260nm – 3500nm |
| OH Content | < 1 ppm | < 120 ppm | < 5 ppm |
| Best Application | Deep UV Lasers, High-end Lens | Drone Optics, Windows, AR Lenses | IR Sensors, Heat Resistance |
2. Deep Dive: Why Choose JGS2 for Your Application?
JGS2 (Synthetic Quartz Glass) is the most versatile “workhorse” in the optical industry. It is produced by melting high-purity natural quartz sand using an oxyhydrogen flame.
- The Sweet Spot of Performance: JGS2 offers excellent transmission from the Ultraviolet (UV) through the Visible and into the Near-Infrared (NIR) spectrum.
- Cost-Effectiveness: While JGS1 is superior in the Deep UV range (<200nm), it is significantly more expensive. For most camera lenses and protective windows, JGS2 provides nearly identical visible light performance at a much more competitive price point.
- Durability: With a high softening point and excellent thermal shock resistance, JGS2 is the ideal substrate for AR (Anti-Reflective) and AF (Anti-Fingerprint) coatings used in outdoor environments.

3. Summary: Which one do you need?
- Select JGS1 if your project involves Deep UV spectroscopy or high-power UV lasers.
- Select JGS2 if you need high-precision optical windows, drone camera covers, or lenses where cost and visible/NIR clarity are balanced.
- Select JGS3 specifically for Infrared (IR) applications where the 2700nm absorption peak must be avoided.
