Product Family Description

  • 15mm and 30mm Diameter Options
  • AR Coated Lenses
  • Mounted Achromatic Pairs Kits Available

Our 15.0mm and 30.0mm Mounted Achromatic Pairs combine our popular TECHSPEC® achromats into common configurations used for relay and projection applications. Packaged in a slim-line aluminum housing, each pair is ready for integration into a host of OEM applications, eliminating the need to handle loose optics. Our 15.0mm pairs can be coupled into our C-mount components using our Helicoid Barrel Accessory. Each lens has also been oriented for optimum system performance. All lenses AR coated. Lower f/# pairs may not be ideal for imaging applications depending on the performance requirements. Cylinder lenses can be incorporated into empty barrels in order to generate lines or sheets of light.
