Precision BK7 Right Angle Prism for Laser Systems | China Suppliers & Factory - 90° Beam Deflection, λ/5 Flatness
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) for visible range transmission; UV Fused Silica for low thermal expansion & laser resistance.
- 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).
- Coatings: AR for 355nm–1550nm (e.g., 532nm, 1064nm); Broadband AR (BBAR) to minimize 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.
