Product Details

  • Unique, 3-Element Design
  • MgF2 Coated
  • Steinheil Triplet Achromatic Lenses also Available

TECHSPEC® Hastings Triplet Achromatic Lenses feature a unique, three-element design that provides distortion free, color-correct viewing. These lenses are computer designed to interact with each other, contributing to the reduction or elimination of “pincushion” distortion, in addition to chromatic and spherical aberrations. TECHSPEC® Hastings Triplet Achromatic Lenses are composed of two concave meniscus elements cemented to a double-convex lens. These lenses are AR coated with MgF2, making them ideal for performance in the VIS range.
