SO-L02 SERIES
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.

Engineering Guidance
Choose the configuration around focal length and working wavelength
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.
