‌Precision Custom Achromatic Lens

●Product Description

1.‌Core Functions‌
●Multi-Wavelength Correction‌: Cemented doublets (‌N-BK7/SF11‌) or triplets achieve ‌<0.1% axial chromatic aberration‌ in ‌400–1100nm‌;
●High Transmission‌: Dual-sided ‌AR/BBAR coatings‌ with ‌<0.5% reflectivity‌ per surface;
●Compact Design‌: Single achromatic lens replaces multiple singlet assemblies, reducing system size ‌>30%‌‌.
2.‌Technical Specifications‌
●Materials & Design‌:
·Cemented Doublets‌: Positive/negative pairs (e.g., ‌N-BK7/F2‌) correct ‌C & F line aberrations‌;
·Air-Spaced Doublets‌: High LIDT (‌>15J/cm² @1064nm‌) for high-power lasers;
·Triplets‌: Three-wavelength correction (e.g., ‌C/F/d lines‌) with ‌<λ/8 RMS wavefront error‌‌.
●Precision‌:
·Surface flatness ‌<λ/5 @633nm‌, slope error ‌<0.5μm/mm‌;
·Diameter tolerance ‌+0.00/-0.02mm‌, CT tolerance ‌±0.05mm‌, eccentricity ‌≤1 arcmin‌;
·Surface quality ‌40-20 scratch/dig‌ (upgradable to ‌10-5‌ ultra-precision)‌.
●Coatings‌:
·Single-Wavelength AR‌: Customized for ‌355nm, 532nm, 1550nm‌ (‌<0.25% reflectivity‌);
·Broadband BBAR‌: ‌350–1200nm‌ range with ‌<0.8% average reflectivity‌;
·Ultra-Broadband AR‌: Covers ‌250–3000nm‌ for multispectral systems‌.
3.‌Applications‌
●Laser Processing‌: Femtosecond laser chromatic compensation for ‌±1μm precision‌;
●Microscopy‌: Fluorescence microscope objectives with ‌<200nm lateral resolution‌;
●Machine Vision‌: Industrial lenses for ‌5MP+ sensors‌, distortion ‌<0.1%‌‌.
4.‌Customization‌
●Material Versatility‌: ‌CaF₂, fused silica, chalcogenide‌ for exotic wavelengths;
●Complex Designs‌: Aspheric-achromatic hybrids, rectangular/annular apertures;
●Fast Turnaround‌: Standard orders in ‌7 days‌, special requests ‌<3 weeks‌‌.

●Differentiation Highlights

●Ultra-Broadband Correction‌: Triplets achieve ‌near-zero dispersion in 400–1600nm‌ for supercontinuum lasers;
‌●Extreme Environment Durability‌: Chalcogenide lenses (‌Ge-As-Se‌) withstand ‌-50°C to 200°C‌ for aerospace optics‌.
