A cylindrical lens is a specialized optical component with curvature along only one axis, used to focus or diverge light in a single dimension.
It is composed of a cylindrical surface and a flat surface (or two cylindrical surfaces), differing from spherical lenses in light refraction characteristics.
Unlike spherical lenses that refract light uniformly in all directions, cylindrical lenses only exert optical effects along their curved axis, with no focusing or diverging action on the flat axis.
Creating a Laser Line Generator
A complete laser line generator is composed of a laser diode and a high-precision cylindrical lens.The line width and coverage are determined by lens curvature and working distance.The laser line projection length can be calculated by：
L=2dtan2θ
