AHL50-40-P-U-780

asphericon AHL50-40-P-U-780 aspheres are high performance aspheric lenses in asphericon quality (RMSi < 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.

Looking for this lens with ultra-precise surface qualities of up to RMSi < 0.015 µm? They are also available from stock. Request your individual offer now!
