AFL25-30-P-U-285

The asphericon AFL25-30-P-U-285 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.
