SO-L23 SERIES

K9 Precision Bi-Convex Lens

SO-L23 precision bi-convex lenses are manufactured from annealed K9 optical glass and cover diameters down to miniature sizes. Their symmetric positive-power geometry is useful for compact relay systems, finite-conjugate imaging, sensor optics and focused illumination where both lens surfaces contribute to convergence.

Product Overview

Configure K9 Precision Bi-Convex Lens around focal geometry and coating

This series should be selected by diameter, focal length and back focal length, with center and edge thickness checked carefully for miniature mounts. The listed equal-surface radius identifies the balanced bi-convex geometry for each model.

Choose this precision series when compact diameters or tighter mechanical integration are more important than the broader economy range of SO-L02.

Optical behavior

This series should be selected by diameter, focal length and back focal length, with center and edge thickness checked carefully for miniature mounts. The listed equal-surface radius identifies the balanced bi-convex geometry for each model.

Selection and integration

Choose this precision series when compact diameters or tighter mechanical integration are more important than the broader economy range of SO-L02.

Need a different diameter, tolerance or coating?

Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
