Product Overview

Configure K9 Plano-Concave Cylindrical Lens around focal geometry and coating

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.

A small angular mounting error rotates the line focus and can dominate system alignment, so include a keyed or adjustable holder where necessary.

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.
