a|FusedSilica Aspheres

Fused silica lenses are optimized for several high-power laser applications, as prototypes in test devices or as standard components for beam focusing or collimation. asphericon offers aspheres made of fused silica in three different quality levels, with superior roughness values, 7 different coatings and also as mounted optics.

a|FusedSilica Aspheres at a glance:

  • Outstanding surface form deviation (RMSi up to ≤ 0.02 µm)
  • High-end finished optics with lowest roughness (Rq ≤ 0.5 nm) for reduced scattering
  • Available with 7 coatings (customized coatings on request)
  • Laser induced damage threshold: 12 J/cm², 100 Hz, 6 ns, 532 nm
  • RoHS compliance
  • Off-the-shelf delivery for short lead times
