UV laser optics lens is divided into spherical lens and cylindrical lens. The curved surface of the spherical lens is a part of the spherical surface, and is divided into a convex spherical lens or a concave spherical lens according to the convergence or separation of parallel light rays. Convex spherical optical lenses are used to correct hyperopia, presbyopia or aphakia. Concave spherical lenses are used to correct myopia. The curved surface of the cylindrical lens is a part of the cylinder. The axis of the cylindrical lens is parallel to the cylinder. There is no refractive power in the direction of the axis and perpendicular to the axis. The direction of the refractive power is the largest, and it is divided into convex cylindrical lenses or concave cylindrical lenses, which are used to correct hyperopia or myopia astigmatism, respectively.
Today we will talk about the cold working process of UV laser optics lens.
The first pass: Milling is to remove the bubbles and impurities on the uneven surface of the lens, (about 0.05-0.08) play a role in shaping.
The second step: the fine grinding process is to remove the damaged layer of the milled UV laser optics lens, and fix the R value laser focusing lens.
The third step: polishing process, is to polish the finely ground lens in one time, this process is mainly to make the appearance better.
The fourth way: cleaning is to clean the polishing powder on the surface of the polished lens to prevent pressure.
No. 5: Edging, is to grind the original outer diameter of the lens to the specified outer diameter.
Step 6: Coating is to coat one or more layers of colored film or other film on the surface of the lens that needs to be coated.
No. 7: Ink, it is necessary to apply a layer of black ink on the outside of the lens to prevent reflection.
Step 8: Gluing is to combine two UV laser optics lenses with opposite R values and the same outer diameter material with glue.
UV laser optics lens is made of a variety of high-hard materials vaporized in a vacuum. According to the principle of light interference, the optical lens can selectively protect the laser lens to increase the transmission of visible light, increase the transmittance of the optical lens, and make imaging It is clearer and can reflect harmful infrared rays and ultraviolet rays. The optical lens greatly improves the surface hardness of the optical resin lens. The UV laser optics lens is much more compact, which is better than similar products on the market.
