  • Coating target is the core technology in the application of band-pass filter materials

    2020-01-17 15:27:23
    Most of the raw materials of filter coating materials are rare metals with very small reserves. With the development of science and technology, the demand of these rare metals has been bullish for a long time. With the continuous promotion of coating technology, the application field of filter technology is also expanding. These metals with excellent physical properties will bring more highlights to our lives with the improvement of our living standards. In the process of filter coating, a transparent electrolyte film or a metal film is coated on the surface of the material by physical or chemical methods, in order to change the reflection and transmission characteristics of the surface of the material. Filter is based on the principle of optical interference. In the visible and infrared band, the reflectivity is between 78-98%, so as to achieve the transmittance. Filter technology has always been an important basic technology in the optical field.

    Shake the polishing paste, pour 4-5 drops onto the cotton ball, and then gently move the lens in a circular manner. Do not press the cotton ball down, the weight of the cotton ball is enough. If too much pressure is applied, the polishing paste will scratch the surface soon. Turn the lens frequently to avoid over polishing in one direction. The polishing time shall be controlled within 30 seconds. At any time, if the color changes, immediately stop polishing, indicating that the outer part of the film is being corroded.

    An inorganic glassy material that transmits light by refraction, reflection, transmission or changes the intensity or spectral distribution of light by absorption is called optical glass. It has stable optical properties and high optical uniformity. Optical glass has high transparency, high uniformity in chemistry and Physics (structure and performance), and specific and accurate optical constants. It can be divided into silicate, borate, phosphate, fluoride and chalcogenide series. There are many kinds of them, mainly according to their positions in the refractive index (nd) - Abbe value (VD) map. Traditionally, all kinds of glasses with Nd > 1.60, VD > 50 and nd < 1.60, VD > 55 are classified as crown (k) glass, and the rest as flint (f) glass. Crown glass is generally used as convex lens and flint glass as concave lens.

    As a precise optical component, the film on the surface of optical filter is easy to be scratched. In addition, our improper cleaning and storage habits in use will also lead to the damage of the optical film on the lens surface, thus reducing the optical performance and service life of the optical filter. Therefore, we can see that the maintenance and storage of optical filters are particularly important in our use.

    The raw materials for the production of laser lens optical glass are some oxides, hydroxides, nitrates and carbonates, and according to the requirements of the formula, phosphate or fluoride are introduced. In order to ensure the transparency of glass, we must strictly control the content of coloring impurities, such as iron, chromium, copper, manganese, cobalt, nickel, etc. It is required to weigh accurately and mix evenly during batching. The main production process is smelting, forming, annealing and inspection.

    No matter the optical lenses made of inorganic or organic materials, in daily use, the friction with dust or grit (silicon oxide) will cause lens wear and scratch on the lens surface. Compared with glass sheet, the hardness of organic material is lower, and it is easier to produce scratches. Through the microscope, we can see that there are two kinds of scratches on the surface of the lens: one is the scratches caused by the gravel, which are shallow and small, which are not easy to be detected by the wearer; the other is the scratches caused by the larger gravel, which are deep and rough around, which will affect the vision in the central area.

  • How to keep the surface of laser lens smooth?

    2019-10-11 16:20:16
    In daily life, lens should avoid contact with high temperature as far as possible, because at high temperature, the film will be damaged or even fall off due to the inconsistency of thermal expansion and contraction between the film and the lens substrate. It should also avoid optical lenses from contacting lenses with strong organic solvents, such as acetone, ether and perfume, because these organic solvents will affect the finish of the lens. The way to place glasses should also form a fixed habit. First, wrap the lenses with flannel cloth, then fold the legs of the lenses. In order to prevent the glasses from being pressed heavily, the glasses can be placed in the hard glasses collection box.

  • Understand that laser lenses can change the direction of light transmission

    2019-09-27 11:38:41
    Laser lenses are glass that can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light. Optical lenses are lenses made of optical glass. The definition of optical glass is glass with uniform optical properties and special requirements for refractive index, dispersion, transmittance, spectral transmittance and light absorption.
  • Small details to be noticed in the use of optical filters in optical glass

    2019-09-20 15:55:54
    Optical filter is an optical device used to select the required radiation band. A common feature of filters is that no filter can make the image of celestial bodies brighter, because all filters absorb certain wavelengths and make objects darker. The filter is made of plastic or glass and special dyes. The red filter can only let the red light pass through, and so on. The transmittance of glass sheet is similar to that of air. All colored light can pass through, so it is transparent. But after dyeing, the molecular structure and refractive index of glass sheet change, and the passage of some colored light changes.
  • How to select and use high quality laser lens correctly?

    2019-09-13 17:22:13
    Laser lenses include optical glass lenses and high refractive index lenses (commonly referred to as ultra-thin lenses), which have high hardness, good wear resistance and low dispersion (usually about 58 dispersion coefficient). Generally, their quality and parameters will not change with time, but the impact resistance and weight of glass lenses are slightly lower than those of resin lenses. Glass lenses, moreover, are not easy to be processed, and it is often more difficult to equip with frame-free and semi-frame glasses. Even if frame-free or semi-frame glasses are processed, they will be particularly vulnerable to damage due to the brittleness of glass in use.
