Please find below our attractive selection of ultra-precise mounted a|Aspheres (with diameters from 12.5 mm to 25.4 mm) which are perfectly aligned (< 10 µm decentration) in high-quality mounts. a|MountedAspheres can either be integrated into exisiting set-ups with common standard holders (e.g. OWIS) or conveniently screwed together with other BeamTuning elements. The mounting thread with an outer diameter of 30 mm allows to simply screw the lens into place. The optics are protected from external inﬂuences by the mount and the corresponding protective caps.
