SO-L09 SERIES
SO-L09 K9 plano-concave cylindrical lenses provide negative optical power in one axis for line expansion, anamorphic beam shaping and astigmatism correction. The economical K9 substrate suits visible laboratory systems, alignment benches and machine-vision illumination assemblies.

Engineering Guidance
Choose the configuration around focal length and working wavelength
Optical behavior
Model selection combines rectangular aperture with negative focal length. Check center and edge thickness, radius and back focal length, and provide rotational alignment so the cylindrical power acts in the intended meridian.
Selection and integration
A small angular mounting error rotates the line focus and can dominate system alignment, so include a keyed or adjustable holder where necessary.
Need a different diameter, tolerance or coating?
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
