K9 Negative Meniscus Lens

SO-L05 K9 negative meniscus lenses introduce negative optical power with two curved surfaces, making them useful for beam expansion, focal-length adjustment and aberration correction in compound imaging systems. Their meniscus form can reduce off-axis aberrations compared with a simple negative singlet in the right orientation.

Product Overview

Configure K9 Negative Meniscus Lens around focal geometry and coating

Selection requires more than focal length: verify both surface radii, back focal length, center and edge thickness, and the sign of the listed dioptric power. Install the lens in the orientation defined by the optical design.

This family is intended for engineered multi-element layouts; reversing the lens can materially change aberration performance.
