Optical lenses requires professional cleaning equipment.
Optical glass is a common optical material with mature manufacturing technology and complete varieties. Generally, optical glass can pass through various colors of light with a wavelength of 0.35~2.5m. Light beyond this range will be strongly absorbed by the optical glass.
There are many places where glass lenses are needed in production and daily life, but can you specifically distinguish optical lenses from ordinary lenses? Let’s take a look:
Ordinary glass: is independent of the chemical composition and the curing temperature region, they obtain through the melt supercooling method, due to the increase in viscosity and has the mechanical properties of solid, and from the liquid state to the glass state of the conversion process is reversible.
Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula. Then it is cooled slowly for a long time to avoid internal stress on the glass block of the laser focusing mirror. After cooling, the glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion meet the specifications. Qualified glass blocks are heated and forged to form the rough shape of optical lens.
The main differences between optical lenses and ordinary lenses are: Optical Lenses supplied from Optical Lens Manufacturer have high transparency, high uniformity of physical and chemical properties and specific and accurate optical constants. These properties cannot be replaced by ordinary lenses.
In the rapid development of science and technology today, the new optical material resin lens, regardless of its optical performance, safety performance, prevent harmful rays to protect the eye performance is far better than ordinary lenses.
The main raw material of optical lens is optical glass, whose refractive index is higher than that of resin lens. Therefore, under the same degree, optical lens is thinner than resin lens. The light transmittance and mechanical and chemical properties of the optical lens are good. Optical lens superior nature, not easy to scratch, high refractive index. The higher the refractive index, the thinner the lens. But the glass piece is fragile, material is biased, when choosing lens frame, should choose a bit smaller lens frame as far as possible, in order to assure those who wear is easy measurable.
In recent years, China has gradually become the world’s important optical glass, optical lens manufacturing base. Foreign enterprises have accelerated their entry into China and set up joint ventures with domestic enterprises. After the tempering of fierce market competition, foreign-funded enterprises have become the main competitors in China’s optical glass manufacturing industry, with private enterprises following closely behind.
The main materials of optical lens are colorless optical glass, colored optical glass, infrared optical materials, crystal materials, glassy materials and plastic materials, etc., which have high transparency, high uniformity of physical and chemical properties and specific and accurate optical constants.
Laser collimating lens cleaning requires professional equipment to clean dirt, grease, sweat, fingerprints and other dirt on the workpiece. During the installation and cleaning of the lens, any sticky material, even nail prints or oil droplets, will increase the absorption rate of the lens and reduce the service life of the lens. Therefore, necessary precautions must be taken when cleaning optical lenses. Lenses should be tested and cleaned in a dry, clean place. Wear finger gloves or rubber gloves to install lenses.
In the process of cleaning the optical lens, it is necessary to remove the contamination of the lens, and do not cause further contamination and damage to the lens. Do not touch the film when taking the lens, but hold the edge of the lens to avoid sharp instruments so as not to cause scratches on the lens surface. First, air balls are used to blow off the floating objects on the surface of the lens. Then, cotton flower balls are dipped in acetone. The lens must be cleaned under light.
The main raw material of optical lens is optical glass, such as Optical Spherical Lens,whose refractive index is higher than that of resin lens. Therefore, under the same degree, optical lens is thinner than resin lens. The transmittance and mechanical and chemical properties of optical lens are good, with constant refractive index and stable physicochemical properties. Both optical lenses or resin lenses, plus a multilayer coating treatment will make glasses feel more comfortable to wear. The principle is that the lens surface coated with magnesium fluoride or quartz and other different refractive index film material, so that the reflection of light interference, can reduce the reflection.
Optical lens superior nature, not easy to scratch, high refractive index. In recent years, China has gradually become an important optical glass manufacturing base in the world. Foreign enterprises have accelerated their entry into China and set up joint ventures with domestic enterprises. After the tempering of fierce market competition, foreign-funded enterprises have become the main competitors in China’s optical glass manufacturing industry, with private enterprises following closely behind.
