Optical lens processing and application in the lens


Optical lenses are divided into spherical lenses and cylindrical lenses. 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 polymerization or separation of the parallel light. The convex Spherical Optical Lens is used to correct hyperopia, presbyopia or aphakic body. The concave spherical lens is used to correct myopia. The curved surface of the Cylindrical Lens is part of the column. The axis of the cylindrical lens is parallel to the cylinder, and there is no refractive power in the direction of the axis. The direction of deflection is the largest, and it is divided into convex column lens or concave column lens, which is used to correct hyperopia or myopic astigmatism.

Today we will talk about the cold working process of optical lenses.

The first track: Milling is to remove the uneven bubbles and impurities on the surface of the lens, (about 0.05-0.08) to form a molding effect.

Track 2: The finishing process is to remove the damaged layer from the milled lens and fix the R-value laser focusing mirror.

The third way: the polishing process is to polish the refined lens in one time. This process is mainly to make the appearance better.

Lane 4: Cleaning, the polished lens will clean the surface of the polishing powder to prevent the pressure.

Track 5: Edge grinding, which is to grind the original lens to the specified outer diameter.

Route 6: Coating is a colored film or other film that is coated with one or more layers on the surface of the coated lens.

The seventh lane: the application of ink, there will be a need for the lens to prevent reflection in the outer Yuan coated with a layer of black ink.

No. 8: Gluing, which is to combine two optical lenses with the same R size and outer diameter as the same material.

The Optical Lens is made by vacuuming a plurality of high-hard materials in a vacuum. According to the principle of interference of light, the optical lens can selectively increase the transmission of visible light by the laser protection mirror, improve the transmittance of the optical lens, and make the imaging clearer. It can also reflect harmful infrared rays, ultraviolet rays, and optical lenses to greatly improve the surface hardness of optical resin lenses. Optical lenses are much more compact than those of similar products on the market.

Optical lenses are widely used in military, scientific research, medical, bioengineering, astronomical observation, etc. The optical lens manufacturing industry has a growth rate of more than 65%. Optical lenses are far ahead in the 14 sub-sectors of the instrumentation industry. The optical lens industry is very hot. A large part of the reason is related to the rapid development of the capacitive touch screen market. The composition and manufacturing process of optical lenses is not only a crucial step in the development of optical instruments, but also a manifestation of a national scientific research strength.

As a multi-component inorganic material, optical lenses have long been unable to understand the relationship between the composition and properties of optical laser collimating lens lenses. It is difficult to create specific properties, using advanced instruments and techniques. The power density of a beam-quality laser can evaporate metal or ceramic products. The intense beam of optical lenses makes lasers a powerful tool, and is increasingly used in industrial and medical applications worldwide.

In the camera lens, lenses made of ED glass are used. Since the wavelengths of the different colors of visible light (red, blue, and green) are different, the refractive index of the optical lens is different, the color depth of the optical lens is adjusted, and the transmittance is adjusted. Eyes are better adapted to changes in ambient light, reduce visual fatigue, protect eyes, and integrate fashion, health and convenience. It is a good lens choice.

The optical lens grade sunglasses are made of resin or PC. When subjected to external impact, only the optical lens will crack and will not burst. The optical lens is made of multi-acrylic, which is easily broken when subjected to external impact. Or eye trauma, multi-layer film containing medical equipment grade not only good image quality, but also 100% blocking UV rays, to avoid eye aging and disease.
