λ/40 Laser Grade Aspheric Lenses

TECHSPEC® λ/40 Laser Grade Aspheric Lenses

  • Substrate Shape and Coating Optimized for Nd:YAG Laser Wavelengths
  • λ/40 RMS Asphere Figure Error
  • Stehl Ratio > 0.8

TECHSPEC® λ/40 Laser Grade Aspheric Lenses are polished through precision magnetorheological finishing (MRF), providing them with an ultra-smooth aspheric surface with an aspheric surface tolerance of λ/40 RMS. The aberration free aspheric surfaces produced through this super-polishing process result in these aspheric lenses having diffraction-limited performance at their design wavelengths. A high-performance Laser Line V-Coat minimizes reflection when these aspheric lenses are used at their Nd:YAG wavelengths. TECHSPEC λ/40 Laser Grade Aspheric Lenses feature substrates designed and shaped at their laser wavelength to optimize the entire lens design, not just the anti-reflection coating, for the laser wavelength. Standard imperial sizes of these laser grade aspheres with f/2 designs, made from fused silica, are available.
