N-BK7 Anti-Reflective Rhombic Prism Factory in China - Zero Beam Deviation, Ideal for Suppliers and Precision Imaging
Product Description
Core Functions
-
Beam Control:
- Parallel Beam Displacement: Monolithic rhombic design achieves zero angular deviation with 1–50mm lateral shift (customizable).
- Anti-Reflection: Dual AR coatings (350–1700nm) with <0.2% reflectivity per surface.
-
Structural Advantages:
- Cement-Free: Eliminates adhesive-induced ghosting/interference.
- Protected Coatings: Internalized AR layers resist abrasion and chemicals (H₂O₂, acid).
Technical Specifications
-
Optics:
- Material: N-BK7 glass (nd=1.5168 @587.6nm), transmission >92% @400–1600nm.
- Surface accuracy: <λ/10 PV @633nm, angle tolerance ±30 arcsec.
- OPD: <λ/8 for distortion-free imaging.
-
Coatings:
- Standard AR: <0.5% reflectivity @400–1600nm (both sides).
- Custom Wavelengths: UV (250–400nm) or mid-IR (2–5μm) AR.
- Ultra-Broadband AR: <0.3% average reflectivity @350–2000nm.
-
Mechanics:
- Size range: 10×10×10mm to 100×100×50mm.
- Chamfer: 0.2mm×45° edges, shock-resistant >10G.
- Mounts: SM2 (2.0"-32) threads or custom holders.
Applications
-
Laser Systems:
- Laser cavity alignment with <5μm beam positioning.
- Femtosecond pulse compressors compensating <5fs² GDD.
-
Optical Metrology:
- Michelson interferometer reference arms (<1nm path stability).
- Machine vision multi-angle beam splitting (0°–60° incidence).
-
Biomedical Imaging:
- Confocal microscope beam steering, eliminating stray light.
- OCT systems with >10dB SNR enhancement.
Customization
-
Specialized Designs:
- Large prisms (>150mm edge) with <λ/20 surface accuracy.
- High-power laser compatibility (>10kW/cm² CW), LIDT >5J/cm² @1064nm, 10ns.
-
Integrated Solutions:
- Embedded piezo stages (PZT) for ±10nm displacement.
- Multi-prism stacks (e.g., dual rhombic) for cascaded beam shifting.
Differentiation Highlights
