SO-L26 SERIES
SO-L26 K9 drum lenses provide strong positive power in a compact body with a cylindrical mounting surface. They are used in fiber launch assemblies, diode-laser collimators, compact illumination modules and optical probes where a ball lens would be harder to position reliably.
Product Overview
Engineering Guidance
Diameter and center thickness define the mechanical envelope; focal length and back focal length determine the source or fiber spacing. The short working distance makes axial tolerance and barrel concentricity especially important.
Use the drum geometry when repeatable mechanical location is a priority in a miniature coupling assembly.
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
