AHL18-15-S-U

asphericon AHL18-15-S-U lenses are high performance standard aspheric components in asphericon quality (RMS < 0.5 µm). They combine the efficiency and the quality of precision-manufactured aspheres with the cost advantage of mass-production. Aspheres based on CNC grinding and polishing manufacture fulfill the highest requirements in terms of quality and tolerances.
