SO-L31 SERIES
SO-L31 UV fused silica negative meniscus lenses provide diverging power while preserving a curved form on both surfaces. They are used to expand beams, correct aberrations in multi-element systems and adjust focal length in UV-visible optical paths that benefit from fused silica.

Engineering Guidance
Choose the configuration around focal length and working wavelength
Optical behavior
The model table includes both surface radii, negative focal length, back focal length and dioptric power. Surface orientation matters because the lens is not symmetric; follow the optical prescription rather than treating it as a generic concave singlet.
Selection and integration
Use fused silica for ultraviolet transmission, low fluorescence or improved thermal stability; confirm coating needs separately for production systems.
Need a different diameter, tolerance or coating?
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
