Application of lens in magnifying glass and reading glasses

　　 Plano-Concave Lenses  is also known as a negative-lens lens. The lens is thin in the middle and thick at the edges. It is also called a concave lens. The concave lens has a diverging effect on the light and can be used as a myopia mirror or an astigmatism mirror. Plano-Concave Lenses 　　The convex lens is made according to the principle of light refraction. The convex lens is a lens with a thick center and a thinner edge. The convex lens is divided into a double convex shape, a  Plano-Convex Lenses  and a concave-convex (or a positive meniscus). The convex lens has a converging light effect, so it is also called a converging lens, and a thick convex lens has a telescopic and converging effect, which is related to the lens. Thickness related, you can do magnifying glass, reading glasses. 　　These features of the lenticular mirror also determine its application in magnifying glasses and reading glasses. 　　We know that the lenticular lens includes a convex lens a...

Optical Part Processing Method

As a  Silicon Domes Manufacturer , let's introduce the processing methods of optical parts. Optical processing can be divided into thermal processing and cold processing. Cold working is the sawing, rough grinding, fine grinding, polishing and centering of the parts. Today, we are going to share with you the related technologies and methods of centering and edging of optical parts processing. The centering of the optical parts is determined by the fact that, for circular optical parts, the size of the side cylindrical surface meets the assembly requirements; for a spherical lens, the alignment of the two spheres (optical axis) and the axis of external symmetry (geometric axis) Deviation (center deviation c: cross center deviation and parallel center deviation). Optical part processing lens centering method: optical centering method (surface reflection like centering method, projection image centering method, spherical center reflection image centering method), mechanical cen...

What is the Difference Between Spherical Lens and Aspheric Lens?

  As a   Spherical Lenses Manufacturer , share with you. It is simple and relatively inexpensive to manufacture a lens whose surface is part of a plane or part of a sphere. Such a lens cannot focus light well; the lack of focus is spherical aberration. Spherical aberration is particularly prominent in large, fast (bright) lenses. This lack of concentration is manifested in various forms of ambiguity. This problem can be corrected by placing other lenses in front of and behind the lens. It can also be corrected by changing the shape of the lens surface (making them aspherical), but this tends to be more difficult and expensive. The aspherical is not. Custom Silicon Spherical Lenses When other lens elements are added as corrections, they increase the amount of glare and reduce the contrast of the photo, and increase the size and weight of the lens. They may also change color slightly. Therefore, an aspheric element usually signals that the lens is finished to produce a contrasti...
