K9 Positive Meniscus Lens

SO-L25 K9 positive meniscus lenses provide converging power in an asymmetric two-curve form. They are used in imaging objectives, relay systems and beam-shaping groups where a meniscus surface prescription helps manage spherical aberration, coma or package geometry.

Product Overview

Configure K9 Positive Meniscus Lens around focal geometry and coating

Model selection should include both surface radii and lens orientation, not only focal length and diameter. Back focal length, center thickness, edge thickness and dioptric power support accurate placement in the final assembly.

The convex and concave surfaces are not interchangeable in use; install the element according to the intended optical prescription.

Selection and integration

The convex and concave surfaces are not interchangeable in use; install the element according to the intended optical prescription.

Need a different diameter, tolerance or coating?

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