Which are Cylindrical Lenses?
Cylindrical Lenses are Non-spherical lenses which include curved faces acting as different sections of a cylinder. With a cylindrical lens, then it compresses the image passing through it and projects it to a line parallel of the intersection. Focusing any light which passes through the lens into a line rather than focusing it on one point; leaving the image completely unaltered. Having these specific attributes, cylindrical lenses are frequently used to fix any ocular astigmatism you might find using another type of lens.
A cylindrical lens provides A standard dimension tolerance limit of +/-0.03mm plus a manufacture limitation of +/-0.01mm. In addition, cylindrical lenses have a standard thickness tolerance of +/-0.02mm plus a manufacture thickness tolerance of +/-0.02mm. More over, More over, a cylindrical lens has a standard surface quality (S/D) comprising 40-20 plus a manufacturing surface quality limit if 10-5. Making these lenses one of the very precise lenses when compared to other designs.
Advantages of Cylindrical Lenses?
The benefit of using a Cylindrical lens is your ability to utilize it for a variety of items. The major reason to use a cylindrical lens is to switch to images size without degrading the image quality. But, cylindrical lenses may also be used for holographic lighting, linear hector lighting, pc, bar code scanning, optical information processing, and laser emissions. Making cylindrical lenses among the most versatile lenses in the market.
In addition, cylindrical Lenses are capable of being customized with certain specifications to meet your needs. These customizations include picking different glass materials, a Different radius, and complex shapes not commonly used for cylindrical lenses. The ability to customize these lenses allows persons to receive the most accurate Results regardless of what they are used for. I.e. Look At This.
