← product overview
SPA_UV-graded-fused-silica

The asphericon AFL25-40-S-U is a standard asphere manufactured from fused silica which can be used both in the UV range as well as for laser applications with high power (> 1kW cw). This asphere combines the performance and quality of precision-polished lenses (RMS <0.3 µm) with the cost advantages of mass production. Thanks to CNC polishing and grinding this aspheric lens meets the highest demands on production quality and tolerance.
