  • What are the advantages of optical filter?

    2020-06-19 09:16:39
    Optical filter is made of plastic or glass and added with special dye. Red filter can only let red light pass through, and so on. The transmissivity of glass sheet is similar to that of air. All color light can pass through, so it is transparent. However, after dye, the molecular structure changes, and the refractive index also changes, and the passage of some color light changes. For example, a white light passing through a blue filter emits a blue light, while the green light and red light are very few, most of which are absorbed by the filter.
  • How to keep the surface finish of laser lens?

    2020-06-12 09:43:13
    In our daily life, we should try our best to avoid contact with high temperature, because under high temperature, the film will be damaged or even fall off due to the inconsistent expansion and contraction of 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 of placing glasses should also form a fixed habit, first wrap the glasses with flannelette, and then close the legs of the glasses. In order to prevent the glasses from being under heavy pressure, the glasses can be placed in the hard glasses collection box.

  • Never use naked fingers to install the lens of optical filter

    2020-05-01 15:18:12
    When the laser cuts the material, the working surface will release a lot of gas and splashes, which will cause damage to the lens. When the pollutant falls on the surface of the lens, it will absorb energy from the laser beam, resulting in the thermal lens effect. If the lens has not formed thermal stress, the operator can disassemble it and clean it. In the process of lens installation and cleaning, any point of sticking, even the nail has been printed with oil drops, will increase the absorption rate of lens and reduce the service life. For example, the following precautions must be taken for daily operation of laser lens:

It focuses on the optimization of product structure, the improvement of product quality, the mastery and innovation of core technology and the expansion of brand influence. Of course, this series of changes require more capital investment from enterprises. For this, laser cutting machine enterprises also need to make a scientific prediction of the future input-output ratio according to their own situation, so as to selectively invest and gradually transition.
  • After fine grinding of optical laser lens with abrasive solution

    2020-04-17 16:00:46
    After the optical laser lens is finely ground by the abrasive solution, there is a crack layer about 2-3m thick on its surface. The method to eliminate the crack layer is polishing. The polishing and grinding mechanism are the same, except that the tool material used is different from the polishing fluid. The materials used for polishing include cloth, polyurethane and pitch. Generally, high-precision polishing surface is required, and the commonly used material is high-grade polishing asphalt. The use of asphalt to polish is to drive the polishing solution to grind the surface of the lens to generate heat through the fine surface of asphalt, so as to melt and flow the glass, melt away the rough vertices and fill the valley bottom of the crack, and gradually remove the crack layer.

    The spectral characteristics of optical filters depend on the band-pass range (half peak and full peak width). In the measurement of color density, the product of the effective spectral sensitivity on the optical path of the densitometer (it is equal to the product of the relative spectral sensitivity SR of the sensor and the transmittance of the measuring filter) and the relative spectral distribution function s of the light source should conform to the standard, in which the spectral radiation of the light source is the standard.
  • The main scene always stands out because of the use of optical filters

    2020-03-06 14:11:37
    The laser lens is made of glass, which is easy to break. So the probability of laser tube rupture is relatively large. How to distinguish the responsibility of the manufacturer or the user when the laser tube breaks? At this time, we need to focus on observing what the laser tube looks like when it is broken. If it is very broken and very open, or it has several sections directly, we don't need to think about the responsibility of the manufacturer. We can be sure that the laser tube will burst when the temperature is too high. You can understand that it will burst after the internal expansion. The reason for the expansion is that there is air in the laser tube, and there is a problem in the water-cooling cycle, so the laser tube is not cooled in time, resulting in the physical effect of thermal expansion and cold contraction of the laser tube.
  • What are the practical applications of optical filters in optical engineering?

    2020-02-28 14:53:57
    In the practical application of optical engineering, not all the places that need band-pass filter are narrower, the better. There is also a part that needs wide-band filter. The so-called band-pass filter is one of many kinds of filters. Filter is a kind of filter that separates a band of monochromatic light from composite light. It has a symmetrical distribution of light transmittance curve and a large transmittance at the center wavelength. At the half of the peak transmittance, the wavelength spacing △ λ of the two symmetrical points on the transmittance curve is the bandpass half width of the filter. It is divided into narrowband filter and wideband filter. It can be used to eliminate the overlap of grating spectral level in spectrograph.
