Precision BK7 Right Angle Prism Factory in China - High-Quality Laser/Optical Systems Suppliers
Product Description
Core Functions
- Beam Steering: Achieves 90° (single reflection) or 180° (double reflection) deflection with ≤±3 arcsec angular error.
- Broadband Compatibility: BK7 covers 350nm–2μm, fused silica supports 190nm–2.1μm.
- Low-Loss Reflection: Reflective coatings (Al, Ag, or dielectric) with >95% reflectivity at target wavelengths.
Technical Specifications
-
Materials:
- H-K9L (N-BK7): High transmission in visible range (400–700nm), cost-effective.
- UV Fused Silica: Low thermal expansion, laser-resistant for high-power systems.
-
Precision:
- Surface flatness λ/5 (@632.8nm), scratch/dig 40/20 (upgradable to 20/10).
- Angle tolerance 90°±3 arcsec, hypotenuse angle 45°±1 arcmin.
- Clear aperture >90%, diameter tolerance ±0.1mm (optional ±0.05mm high-precision).
-
Coatings:
- Anti-Reflective (AR): Single/dual-sided for 355nm–1550nm (e.g., 532nm, 1064nm).
- Broadband AR (BBAR): Minimizes reflection loss in UV/IR bands.
Applications
- Laser Systems: Beam combining/splitting or path redirection in fiber lasers.
- Optical Instruments: Mirror substitutes in microscopes or telescopes.
- Industrial Metrology: Beam alignment in 3D scanners or LIDAR.
Customization
- Optical Subassemblies: Bonded with polarizers or waveplates for modular optics.
- Protective Finishes: Black lacquer (e.g., GT-7) shields non-optical surfaces.
- Fast Turnaround: Standard orders in 7 days, special requests <3 weeks.
Differentiation Highlights
✓ Ultra-High Angular Precision: ±3 arcsec tolerance calibrated via interferometry for metrology systems.
✓ Multi-Material Versatility: Fused silica resists 10.6μm CO₂ lasers, BK7 optimizes visible imaging.
