SO-L33 SERIES
SO-L33 UV fused silica ball lenses provide very short focal lengths in a compact spherical geometry. They are commonly used for fiber coupling, diode-laser collimation, compact illumination and miniature optical probes that benefit from ultraviolet transmission and low fluorescence.

Engineering Guidance
Choose the configuration around focal length and working wavelength
Optical behavior
Ball-lens performance is strongly linked to diameter, refractive index and source numerical aperture. Use the listed focal length and back focal length to estimate working distance, and account for the very small clearances typical of miniature models.
Selection and integration
Precise centering is critical: decenter or axial spacing error can dominate coupling loss in a ball-lens assembly.
Need a different diameter, tolerance or coating?
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
