Precision Custom Achromatic Lenses from China Suppliers - High-Quality Factory Solutions for UV-NIR Optics
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.
