WebCylinder lenses are most commonly used in laser beam shaping to correct an asymmetric beam, create a line, or generate a light sheet. Modern scientific methods such as Particle Image Velocimetry (PIV) and Laser Induced Fluorescence (LIF) often require a thin laser line or an even laser light sheet. great story ideas for kidsWebthe optical axis. If a cylinder lens is ro-tated along its optical axis, the profile of the lens would change dramatically. For this reason, cylinder lenses require a unique coordinate system to effectively reference features of a lens. The refer-ence system is defined by two orthogo-nal axes – the plano axis and power axis. great story in the bibleWebminus cylinder lens used to have the cylinder surfaced on the back side of the lens.
