A|FUSEDSILICA ASPHERES WITH EVEN BETTER SURFACE ROUGHNESS!
Discover also the a|FusedSilica product lines: Precision, Ultra and BeamTuning. Optimized for a wide range of (laser) applications, as prototypes in test devices or as standard components for beam focusing/collimating, our fused silica aspheres are particularly suitable for high laser powers. Besides additional diameters, all a|FusedSilicas are also available with high-precision V-coatings (355 nm, 532 nm and 1064 nm).
a|FusedSilica aspheres at a glance:
- Precison Line: RMSi ≤ 0.5 μm and wavefront RMS ≤ 235 nm perfectly tailored for your UV application
- Ultra Line: ultra-precision optics with surface form deviation ≤ 0.3 μm and wavefront RMS ≤ 140 nm
- BeamTuning line: high-end finished optics for lowest roughness of ≤ 0.5 nm, RMSi ≤ 0.02 μm and wavefront RMS ≤ 10 nm
