Traditional CNC polishing techniques cannot achieve the required
irregularity in the aspheric lens to the diffraction-limited design

Specifications for Precision Asphere - CNC-Polished

  • Irregularity <750nm RMS
  • Wavefront error: <500nm RMS

Specifications for Diffraction Limited High-Precision Asphere – MRF Polished

  • Irregularity: <55nm RMS
  • Slope: <200µrad PV
  • Wavefront error: Diffraction limited
  • Slope & Irregularity specifications are chosen to produce a diffraction limited wavefront error

Thorlabs can now offer two product lines.
