The purpose of developing Air-Spaced focusing lenses is to minimize aberration and achieve a smallest spot size. The achromatic triplet focusing lenses are color corrected; both working laser beam and inspection visible beam will focus on a same focus point or two closest ones.
Our Ronar-Smith YAG focus lenses are high-precision optical components engineered for industrial laser systems operating at 1064nm, 532nm, 355nm, and 266nm wavelengths. Designed for laser marking, cutting, welding, and drilling applications, these lenses deliver sharp, uniform focusing with minimal aberration and high damage threshold.
Key Features
Multi-Wavelength Compatibility：Available for 1064nm, 532nm, 355nm, and 266nm laser systems, with achromatic options for dual-wavelength use (e.g., 1064/635nm).
Dual/Triplet Designs：Choose from doublet or triplet configurations for optimized focusing performance and reduced chromatic aberration.
Wide Focal Length Range：Focal lengths from 24mm to 250mm to suit different working distances and spot size requirements.
High Precision Optics：Precision-ground lenses with anti-reflection (AR) coatings for maximum transmission and low reflection losses.
Industrial-Grade Construction：Rugged housing options, including models with protective windows for harsh environments.
Flexible Specifications：Multiple diameters, clear apertures, and working distances to match various laser system setups.
