SO-L32 SERIES
SO-L32 UV fused silica drum lenses combine spherical optical surfaces with a cylindrical sidewall that is easier to locate and retain than a full ball lens. They are useful for compact fiber coupling, miniature collimators and UV-visible optical probes requiring a short focal length.
Product Overview
Engineering Guidance
The model geometry is defined by diameter and center thickness, while focal length and back focal length establish the optical spacing. The cylindrical barrel improves mechanical registration but still requires accurate centering relative to the optical axis.
Choose a drum lens when ball-lens-like power is needed with a more practical cylindrical mounting surface.
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
Technical Resources
Selection notes and practical guidance matched to this product family.
Relate effective focal length, back focal length and lens orientation to focusing and collimation performance.
Compare transmission, thermal behavior and cost before choosing a substrate for a precision lens.
Use geometric and surface specifications to confirm optical fit, mounting depth and expected image quality.
