    It is necessary to blow off the floating objects on the surface of the element by air ball, especially the lens with small particles and flocs on the surface. But never use compressed air on the production line, because the air contains oil and water droplets, which will deepen the pollution to the lens.

    Optical filter is an optical device used to select the required radiation band. One common feature of filters is that no filter can make the image of the celestial body brighter, because all filters absorb certain wavelengths, making the object darker.
  • Application of optical filter in solid state laser filters

    2021-05-21 16:15:28
    Optical filter is made of plastic or glass and special dye. Red filter can only let red light pass through, and so on. The transmissivity of glass is almost the same as that of air. All colored light can pass through it, so it is transparent. However, after dyeing with dye, the molecular structure and refractive index will change, and the passing of some colored light will change. For example, when a beam of white light passes through a blue filter, it emits a beam of blue light, while the green light and red light are very few, and most of them are absorbed by the filter.

    2021-04-30 15:26:24
    The glass that can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light is called optical glass. The components composed of optical glass are the key components in optical instruments. Optical glass is the foundation and important part of optoelectronic technology industry. In today's society, with the continuous integration of optics, electronic information science and new material science, the application of optical glass as the basic material of Optoelectronics in the three fields of optical transmission, optical storage and optoelectronic display is advancing by leaps and bounds. Optical glass is widely used in all aspects of information acquisition, transmission, storage, conversion and display of optoelectronic products, This effectively promotes the development of optical glass to a higher level.

    The uniformity of optical filter film thickness refers to the change of film thickness with the change of substrate surface position. If the film thickness uniformity is not good, the film characteristics will be seriously damaged, so the film thickness uniformity is as important as the film thickness monitoring.
  • Different laser lenses often have different uniformity requirements

    2021-04-16 15:25:12
    Optical thin films are formed on the substrate by solid-liquid-gas-solid or solid-gas-solid transformation of bulk materials, so their microstructure, crystal structure and film composition are different from the original bulk materials.

    An inorganic glassy material that transmits light by refraction, reflection and 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 homogeneity 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. They are classified according to their position in the refractive index (nd) - Abbe value (VD) diagram. Traditionally, the glasses with Nd > 1.60, VD > 50 and nd < 1.60, VD > 55 are classified as crown (k) glass, and the others as flint (f) glass. Coronal glass is generally used as convex lens, flint glass as concave lens.
  • What kind of optical filter can meet the requirements of work

    2021-03-12 16:16:32
    In daily life, resin lenses should be avoided from contacting high temperature as possible, because the thermal expansion and contraction of the film and resin lens substrate are inconsistent under high temperature, which will cause the damage or even falling off of the film. In addition, the resin lenses should be prevented from contacting strong organic solvents, such as acetone, ether and perfume, because these organic solvents will affect the surface finish of resin lenses. In addition, the way to place glasses should also form a fixed habit. First, wrap the resin lens with aspheric lens flannelette, then close the leg of the mirror. In order to prevent the glasses from being stressed, the glasses can be placed in hard glasses collection box.
