K9 Bi-Convex Lens

SO-L02 K9 bi-convex lenses provide positive optical power for finite-conjugate imaging, beam focusing and general laboratory assemblies. With two convex surfaces, they are a practical choice when the object and image distances are comparable and a symmetric lens form offers better aberration balance than a plano-convex element.

Product Overview

Configure K9 Bi-Convex Lens around focal geometry and coating

The range includes many diameter and focal-length combinations. Match the clear aperture to the beam, use the effective focal length to set system power, and confirm back focal length plus center thickness before finalizing the mount.

Orient either surface toward the source when the conjugates are symmetric; for a nearly collimated beam and strongly unequal conjugates, compare performance with a plano-convex lens.

Optical behavior

The range includes many diameter and focal-length combinations. Match the clear aperture to the beam, use the effective focal length to set system power, and confirm back focal length plus center thickness before finalizing the mount.

Selection and integration

Orient either surface toward the source when the conjugates are symmetric; for a nearly collimated beam and strongly unequal conjugates, compare performance with a plano-convex lens.

Need a different diameter, tolerance or coating?

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