SO-L07 SERIES
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

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