What is the Processing Form of Optical Glass?

  As a   Professional Optical Dome Manufacturer , share with you. In order to produce high quality optical glasses with uniformity, special preventive measures must be taken. First use fairly pure raw materials and equipment, which are carefully designed to avoid pollution of harmful substances. Typically, block glass is made by filling a certain amount of glass melt into bulk, then placing it in molten form for a period of time to settle, and then slowly cooling it to solidification at a carefully controlled rate. Slow cooling allows annealing, that is, reducing internal mechanical stress. Very slow and well-defined annealing stages are important, especially for bringing stress-induced birefringence to very low levels, as well as for reaching constant refractive index values. Precision optical glass is usually provided in the form of fine annealed glass, with a reference annealing rate of K /h.2, for example. Glass Optical Domes Other forms of supply of raw optical glass are ...

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...

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...
