Core Pain Points We Solve
Bubbles & striae in low-grade quartz cause beam distortion in precision optical systems
Ordinary glass cracks under high temperature and rapid thermal shock cycles
Single substrate cannot cover deep UV, near UV and infrared multi-spectrum requirements
Hard to source quartz with custom cutouts, drilling, grooving and wavelength-specific AR coating
Key Features
Custom Dimensions & Freeform Shapes
No standard stock sizes. Fabricate per your drawing, sample or specs: round, rectangular, oval and irregular profiles.
Optical Grade High Purity
Bubble & striae controlled fused silica for distortion-free UV / IR light transmission.
Superior Thermal Shock Resistance
Near-zero thermal expansion, stable operation under cycling high-temperature environments.
Broadband Optical Transmission
Covers deep UV, visible and mid-infrared bands to match multi-aperture optical designs.
Excellent Chemical Inertia
Resistant to most acids and solvents, suitable for corrosive lab and industrial environments.
Precision Optical Machining
CNC drilling, grooving, chamfering, single / double-sided polishing to tight flatness & parallelism tolerances.
