Product Family Description

  • Aspheric Surface Accuracy of 0.25μm RMS
  • 0.66 and 0.50 NA Lenses
  • Complete Metrology Data Included

Our TECHSPEC® Calibration Grade Precision Aspheric Lenses offer the ultimate in performance and precision available from an off-the-shelf polished aspheric lenses. Featuring improved aspheric surface figure, surface quality, and centering specification over our TECHSPEC® Precision Aspheric lenses, these optical components are ideal for integration into R&D and OEM applications alike. With high numerical apertures, the lenses are ideal for improving the efficiency of low light level detection systems, or for applications requiring a compact optical path.

Each aspheric lens is serialized and provided with a complete metrology data package. The test data package includes a surface profile performed on our Taylor Hobson Talysurf Profilometer, an interferogram of the spherical surface, and tested values for diameter, center thickness, and centration. For custom designed calibration grade precision aspheric lenses, coating requirements, or volume pricing, please contact our Sales Department.
