ZnSe Cylindrical Lenses
ZnSe cylindrical lenses for one-axis CO2 laser beam shaping, line generation, and IR scanning optics. Share axis and focal length.
Product Overview
Overview
ZnSe cylindrical lenses focus or expand light in one axis only. They are used to form line beams, correct astigmatism, or shape CO2 laser and infrared beams in one dimension.
Optical Function
Unlike spherical lenses, cylindrical lenses act on a single axis. This makes them useful for line generation, one-axis magnification, scanner optics, and beam shaping layouts that require directional control.

Engineering Notes
Before release, confirm axis orientation, focal length, line length target, clear aperture, and coating needs. These details usually determine whether a cylindrical lens will match the scanner or beam-shaping layout.
