Product Detail

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;
