  • How to judge the optical filter products as good products?

    2021-04-23 15:40:07
    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.

    2021-04-02 14:25:40
    Optical filter is made of plastic or glass and special dye. 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 change, and the passing of some colored light changes. 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.

    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.
  • What are the application of laser lens in automobile?

    2021-03-05 17:04:58
    Laser welding of laser lens has become one of the important means in automobile manufacturing because of its advantages of high energy density, small deformation, narrow heat affected area, high welding speed, easy to realize automatic control and no subsequent processing. There are hundreds of thousands of parts in a car body and chassis. How to connect them together has a direct impact on the rigidity of the vehicle body. Laser welding can connect all kinds of metal materials of different thickness, brand, type and grade together, while improving the production efficiency and quality, and increasing the flexibility of vehicle design and material selection.
  • Small details in using optical filter of optical glass

    Optical filter is used to select the required radiation band of optical devices. One of the common characteristics of filters is that no filter can make the image of celestial bodies brighter, because all filters will absorb certain wavelengths and make objects darker. The filter is made of plastic or glass and special dye. The red filter can only let the 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 change, and the passing of some colored light changes.
  • Optical lens and optical filter play an important role in optical instruments

    Generally speaking, optical lenses are made of optical glass, which are mainly used in optical instruments. Optical instruments are composed of single or multiple optical devices. Optical instruments are mainly divided into two categories: one is optical instruments for real image, slide projector, camera, etc., and the other is optical instruments for virtual image, such as telescope, microscope, magnifying glass, etc Optical instruments play an important role and can not be ignored.

    The laser lens has good directivity. In the space of the emission direction, the light energy is highly concentrated, so the brightness of the laser is 10 million times higher than that of the ordinary light, or even hundreds of millions of times. Moreover, because the laser can be controlled, the light energy is not only highly concentrated in space, but also highly concentrated in time, so it can produce a huge light and heat in a moment, and become a strong and invincible beam.

    Optical filter is a strange concept for many people. It seems that it is far away from our daily life, but it is not. If we observe our surroundings carefully, we will find that many aspects of our life are inseparable from filters: for example, there are antireflection filters on the myopia lenses for correcting eyesight, the high reflection filters on the car mirrors, and the core components of projectors widely used in business offices are more than a collection of various filters.
