Product Family Description

  • Color Corrected at 632.8nm and 1064nm
  • Optimized to Reduce Spherical Aberration
  • Minimizes Spot Size for Materials Processing

TECHSPEC® Nd:YAG Air-Spaced Achromatic Focusing Doublets achieve diffraction limited performance at 1064nm. These lenses are designed for use with high power Nd:YAG laser systems utilizing a HeNe laser for alignment and also for laser welding and processing of aluminum, steel, and plastics. Filling the performance gap between more economical single element spherical lenses with worse performance and aspheres with diffraction limited performance, these lenses provide achromatic performance that single lens element solutions cannot. TECHSPEC® Nd:YAG Air-Spaced Achromatic Focusing Doublets are ideal in aluminum, plastic, and other material laser processing applications.
