Customized Irregular-shape Quartz Optical Windows JGS1/JGS2/BF33
Grade
Customized irregular quartz optical windows are engineered from
high-purity silicon dioxide (SiO₂), designed to address complex
optical system requirements by breaking traditional geometric
constraints (e.g., circular/square formats). These windows support non-standard shapes such as ellipses,
polygons, and free-form curves. Core advantages include high-temperature resistance (1,100°C
continuous use), low thermal expansion coefficient (5.5×10⁻⁷/°C),
broad-spectrum transparency (185–3,500 nm), and chemical inertness,
making them ideal for extreme environments in precision optical
devices. ZMSH specializes in full-cycle customized production, offering
end-to-end services from design to delivery, serving high-end
sectors such as semiconductors, laser technology, and aerospace.

Key Features of Irregular-Shaped Quartz Glass Windows
1. Geometric Customization
Supports non-standard geometries (ellipses, rectangles, hexagons,
stars) with minimum processing size of 0.1 mm and ±0.02 mm
tolerance.
Enables specialized optical designs, including asymmetric systems
and microfluidic chip windows.
2. High-Temperature Performance
Softening point: 1,730°C; long-term operational stability up to
1,100°C; short-term tolerance up to 1,450°C with rapid thermal
cycling.
3. Chemical Stability
Resists strong acids (excluding HF), exhibiting 30× greater acid
resistance than ceramics and 150× higher than stainless steel.
4. Optical Properties
Transmittance: ≥93% in visible range, ≥90% in UV (185 nm), and
≥85% in IR (3,500 nm).
Spectral Coverage: Three material grades (JGS1/JGS2/JGS3) for
UV to IR applications.
5. Mechanical Properties
Mohs hardness: 5.5–6.5; compressive strength: 1,100 MPa; flexural
strength: 67 MPa.
6. Surface Treatments
Custom coatings: anti-reflective (AR), reflective, hydrophobic, and
laser-damage-resistant films.
Primary applications of Irregular-Shaped Quartz Glass Windows
1. Semiconductor Manufacturing: Asymmetric observation windows
in wafer etching equipment for high-temperature CVD processes.
