Optical Design

What is a Cylindrical Lens?      Like all lenses, this lens focuses light, but it differs in that it focuses the light in a line instead of to a single point as a spherical lens does. The curvature of a Cylindrical lens is sectioned so when the light passes through it is projected onto a line that intersects the surface in a parallel fashion and on a plane tangent. The lens compresses the image so that it is perpendicular to the line and projects the image in a parallel direction. This cylindrical lens is often the solution for people who have ocular astigmatism. The Eye Correction Capabilities      A Cylindrical lens is not shaped like a spherical lens, because of this, the cylindrical lens is used in many industries.It can be used in barcode scanning, holographic applications, linear detection, laser emissions, and of course there are many optical uses, as well as many. Other uses. Cylindrical Lens Use      Shanghai Optics is a manufacturer of cylindrical
