Precision Custom Achromatic Lens from China Factory – Reliable Suppliers for UV-NIR High-Resolution Optics

Discover ALHAZEN's precision achromatic lenses, expertly crafted by a leading factory in China. These lenses utilize advanced cemented doublet and triplet designs to effectively eliminate chromatic and spherical aberrations, achieving a remarkable focal length tolerance of <±1% and a clear aperture of ≥95%. Optimized for the UV-NIR wavelength range of 300–1600nm, they are perfect for high-resolution imaging, laser collimation, and precision optics. As a trusted supplier, ALHAZEN delivers exceptional quality and performance in every lens.

Product Detail

●Product Description

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%.

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.

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%.

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.
