How to solve the orange peel on the lens?

The optical lens we often say is a device that aggregates or disperses light, usually composed of a piece of glass, but similar devices used for other electromagnetic radiation are usually also called lenses. What are the two types of optical lenses? And how to solve the orange peel of the lens?

What are the two types of optical lenses?

An optical lens is an optical element made of a transparent material (such as optical glass, resin, etc.) as a part of a spherical surface made according to the law of light refraction. At present, the commonly used optical lenses on the market are composed of several lenses. Generally, the lens structures used for optical lenses are: 1P, 2P, 1G1P, 1G2P, 2G2P, 4G, etc. The more lenses, the higher the cost.

Therefore, a high-quality camera should use a glass lens, and its imaging effect is better than a plastic lens. It plays an important role in astronomy, military, transportation, medicine, art and other fields. Lenses can be widely used in various fields such as security, automotive, digital cameras, lasers, and optical instruments.

With the continuous development of the market, lens technology has become more and more widely used. Optical lenses are made according to the law of light refraction. A lens is an optical element made of transparent materials (such as glass, crystal, etc.). The lens is a refracting lens, and its refractive surface is a transparent body with two spherical surfaces (part of the spherical surface) or one spherical surface (part of the spherical surface) and one plane. The objective lens, eyepiece and condenser lens are composed of single and multiple lenses. According to the difference of its shape, it can be divided into two categories: convex lens (positive lens) and concave lens (negative lens).

How to solve the orange peel of the optical lens?

The orange peel of the optical lens will cause the optical lens to have a great influence in use. Therefore, we need to go through a special processing technique during the processing of the optical lens to avoid orange peel. We can control the rotation speed of the grinding wheel so that no obvious marks will be produced during the grinding process of the optical lens.

Through polishing with a polishing machine, the surface of the lens will not produce orange peel. Water is used for real-time cooling during the grinding process, and the debris generated by the grinding is removed with a fan, so that the lens will not be caused by debris during processing. The lens is damaged, thereby increasing the yield of the optical lens.
