SO-L07 SERIES

K9 Plano-Concave Lens

SO-L07 K9 plano-concave lenses are negative focal-length elements for beam expansion, focal-length extension and divergence control. The broad model range supports compact laser expanders, alignment systems, educational optics and custom imaging assemblies that need economical negative power.

Product Overview

Configure K9 Plano-Concave Lens around focal geometry and coating

Choose the negative effective focal length according to the required divergence, then confirm diameter, back focal length and edge thickness. In collimated-beam use, the curved surface normally faces the incoming beam.

Use SO-L07 for the GLH13 dimensional system; it remains separate from other K9 plano-concave families so model suffixes stay unambiguous.

Optical behavior

Choose the negative effective focal length according to the required divergence, then confirm diameter, back focal length and edge thickness. In collimated-beam use, the curved surface normally faces the incoming beam.

Selection and integration

Use SO-L07 for the GLH13 dimensional system; it remains separate from other K9 plano-concave families so model suffixes stay unambiguous.

Need a different diameter, tolerance or coating?

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