    After fine grinding with grinding fluid, the surface of optical quartz lens still has a crack layer about 2-3m thick. The method to eliminate this crack layer is polishing. The polishing mechanism is the same as that of grinding, except that the tool material used is different from that of polishing fluid. The materials used for polishing include flannelette (cloth), polishing leather (polyurethane) and asphalt (pitch). It is usually necessary to achieve high-precision polishing surface, and the commonly used material is high-grade polishing asphalt.

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

    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

    2021-07-16 16:05:23
    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.
  • How to keep the laser lens clean
