Precision BK7 Right Angle Prism for Laser Systems - China Suppliers & Factory - 90° Beam Deflection, High 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) high transmission in visible range (400–700nm); UV Fused Silica low thermal expansion, laser-resistant.
- Precision: Surface flatness λ/5 (@632.8nm), scratch/dig 40/20 (upgradable to 20/10); Angle tolerance 90°±3 arcsec.
- Coatings: Anti-Reflective (AR) for 355nm–1550nm; Broadband AR (BBAR) minimizes reflection loss.
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.
