Product Family Description

  • Higher Precision Versions of Our Precision Aspheric Lenses
  • 0.25μm RMS Aspheric Figure Error
  • High Numerical Apertures to Maximize Throughput

TECHSPEC® High Precision Aspheric Lenses are CNC polished aspheric lenses that feature a 0.25µm RMS aspheric figure error. The precision aspheric figure error makes these lenses ideal for applications that require spherical aberration correction, including imaging and laser focusing applications. These aspheric lenses can also be used to replace multiple spherical elements in optical assemblies to reduce weight and cost. TECHSPEC High Precision Aspheric Lenses are available with diameters from 10 to 50mm and high numerical apertures to maximize light throughput.
