Precision BK7 Right Angle Prism for Laser/Optical Systems

●Product Description

1.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.
2.‌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.
3.‌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.
4.‌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.
