‌N-BK7 Anti-Reflective Rhombic Prism

‌N-BK7 Anti-Reflective Rhombic Prism

ALHAZEN’s N-BK7 anti-reflective rhombic prism features ‌monolithic construction‌ with ‌zero beam deviation at 45° incidence‌. AR-coated for ‌<0.5% reflectivity @400–1600nm‌, ideal for laser beam splitting, interferometry, and precision imaging‌.

    Product Description

    1.‌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)‌.
    2.‌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.
    3.‌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.
    4.‌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

    ●Nanometer-Level Precision‌: Profilometer QC guarantees ‌±0.02mm diameter tolerance‌ for micro-optics;
    ●High-Index Versatility‌: Materials like ‌SF11‌ enable ‌short focal lengths‌ for compact optical designs‌.
