  • Color filters play an important role in photography and are widely used

    2021-07-23 16:52:02
    Color filter is an optical device used to select the required radiation band. A common feature of filters is that no filter can make the imaging of celestial bodies brighter, because all filters will absorb certain wavelengths, making objects darker. The filter is made of plastic or glass with 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, and all colored light can pass through, so it is transparent. However, after dyeing with dye, the molecular structure changes, the refractive index also changes, and the passage of some colored light changes.
  • Photographic color filter is a special case of optical filter

    The color filter selectively transmits light in a specific wavelength range, while absorbing the rest. They usually block longer and shorter wavelengths (bandpass) only by long wave pass, short wave pass or wavelength band. The passband can be narrower or wider; The transition or cutoff between the maximum and minimum transfers can be sharp or gradient. There are filters with more complex transmission characteristics, such as having two peaks rather than a single band; These are usually older designs traditionally used for photography; More regular filters are used in scientific and technical work.

  • How to choose optical filter in optical devices?

    2021-07-02 16:24:26
    Optical filter is used to select the required radiation band of optical devices. Optical filter is made by adding special dye into plastic or glass substrate or evaporating optical film on its surface, which is used to attenuate (absorb) some light bands in the light wave, or to accurately select a small range of light waves to pass through, while reflecting (or absorbing) other unwanted wave bands. By changing the structure of the filter and the optical parameters of the film, various spectral characteristics can be obtained, so that the optical filter can control, adjust and change the transmission, reflection, polarization or phase state of light wave.

    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.

    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.

    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.

    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.
