WebCylinder lenses are crucial to a wide range of laser applications including circularizing elliptical beams from a laser diode, focusing a diverging beam onto a linear detector array, creating a light sheet for measurement … WebCylindrical Lenses. Cylindrical lenses focus or expand light within a single axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic, laser diode, acousto-optic and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam.
