China N-BK7 Anti-Reflective Rhombic Prism Suppliers - Zero Beam Deviation, AR Coated for Precision Imaging Factory
Product Description
-
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).
-
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.
-
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.
-
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.
