  • Never Handle The Optical Lens Of Laser Cutting Machine Directly To Protect The Lens

    2019-04-11 13:38:51
    When the laser cuts the material, the working surface will release a lot of gas and spatter, which will cause damage to the lens.When the contaminant falls on the surface of the lens, it absorbs energy from the laser beam, causing the thermal lensing effect.If the lens has not formed thermal stress, the operator can remove it and clean it.During the installation and cleaning of the lens, any sticky material, even oil droplets printed on the nail, will increase the absorption rate of the lens and reduce the service life.As an example, the following precautions must be taken in daily operation of laser lenses:
  • Different Films Of Optical Window Filters Have Different Uniformity Requirements

    2019-04-11 13:38:17
    Laser cutting machine in the cutting process, auxiliary gas is essential!Among them, we often use oxygen and nitrogen. Of course, the higher the purity of the gas, the better the cutting quality.There are also many customers who want to use air cutting to save costs. However, there is always water mist on the protective lens during the cutting process, and the cutting quality is poor. Why?

    Filters are very useful.Widely used in photography.A color filter is an optical filter that represents a color. It can accurately select the small range of light waves that it wants to pass through, while reflecting off other unwanted waves.Color optical filters are usually mounted in front of the light source to allow the human eye to receive saturated light of a certain color.
  • What Are The Advantages Of Ar Filters In Our Optical Window Filters?

    Optical filter in addition to the central wavelength drift caused by moisture absorption, high temperature rise caused by the change of the film refractive index, and the change of the thickness of the membrane is a thermal expansion led up will cause the change of membrane layer optical thickness, that resulted from the center wavelength drift. Not only that, due to the substrate of the thermal expansion coefficient of thermal expansion coefficient and film system is different, in the case of heat, film system will be affected by the interaction between the substrate stress and elastic deformation, which aggregate density changes, can also lead to central wavelength drift.

    2019-04-11 11:54:30
    Optical filters are a strange concept to many people. They seem to be far away from our daily life, but they are not.Look carefully around, we will find life is closely connected with filter: in many ways such as vision correction of myopia have minus reflection filter on the mirror, car mirrors with high reflection filter, widely used in the business office projector core components but also brings together a variety of filters, went to the hospital to check body using biochemical detector is one of the core parts of monochromator many are using narrowband filter, digital camera is used in the long wave pass filter, short wave pass filter, all kinds of optical instruments, liquid crystal displays and anti-counterfeiting technology, optical communication, laser technology and so on all is closely connected with the development of filter technology.It can be said that without the development of filter technology as the foundation, many modern emerging technologies are difficult to achieve the current achievements.
  • There Are Several Advantages To Using Uncoated Metal As An Optical Protective Windows Filter

    2019-04-11 11:53:50
    Other uncoated metals widely used in infrared reflectors are gold and silver.Using solid gold or silver as mirrors is impractical (not to mention extremely expensive).In contrast, this rare metal is often used as a vacuum or electroplating film on other substrates.Their inherent reflectivity is higher than that of copper or molybdenum: at 10.6 m wavelengths, gold typically has a reflectivity of 99.0% and silver 99.2%.However, they have the same weaknesses, such as being more flexible than other metals.
  • What Are The Characteristics Of Laser Optical Lenses In Practical Use?

    2019-04-11 11:53:20
    The main feature of filters is that they can be quite large.The film filter is divided into two types: the film absorption filter and the film interference filter.The former is a chemical etching on a specific material substrate so that the absorption line is located at the desired wavelength.Generally through the longer wavelength, more used as an infrared filter.The latter is in a certain film base, with vacuum coating method alternately formed with a certain thickness of high refractive index or low refractive index of metal-dielectric - metal film, or the full dielectric film, constitute a low-level, multi-stage series solid fabry-perot interferometer.Choice of film material, thickness, or series type is determined by the desired central wavelength or transmission bandwidth lambda.
  • Optical Protective Windows Filters Are Used To Limit The Light To The Band Of Interest

    2019-04-11 11:52:41
    Optical filters are devices that selectively transmit light of different wavelengths, usually using flat glass or optical plastics. These optical products are processed by coating technology and have interference coating.The optical properties of the filters are described solely by their frequency response, which specifies how the amplitude and phase of each frequency component of the input signal is modified by the filters.
  • Photographic Color Optical Windows Filters Are a Special Case Of Optical Filters

    2019-04-11 11:52:03
    Color filters selectively transmit light over a specific wavelength range while absorbing the rest.They can usually only pass through the long, short or wavelength band, blocking the longer and shorter wavelengths (bandpass).The passband can be narrower or wider;The transition or cutoff between the maximum and minimum transfers can be sharp or gradual.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 for scientific and technical work.

    Optical glass is measured by optical instruments to verify whether purity, transparency, uniformity, refractive index and dispersion are in conformity with specifications. Qualified glass blocks are heated and forged to form optical lens hair germs. Then through the production, processing and testing of each process, the qualified optical lenses are finally formed. Optical lenses have high transparency, high uniformity of physical and chemical properties, and specific and accurate optical constants. These performances can not be replaced by ordinary lenses.
  • What Are The Two Optical Lens Filters Used In Installation?

    2019-04-11 11:48:25
    Optical filters are optical devices used to select the desired radiation bands.Optical filters are very useful and are widely used in photography.There are two types of optical filters. One is colored or colorless optical glass mounted on the lens. For the sake of clarity, we call it a filter.The filters can be classified according to their photographic purposes: black and white photographic filters, color photographic filters, black and white Shared filters, special effect filters.The other is a strobe filter used in front of the flash to adjust the overall or partial tone of the subject to produce a particular color.
  • In the ordinary use of optical filters in the process should be as careful as possible

    2019-04-11 11:47:45
    Optical filters are optical devices used to select the desired radiation bands.One thing filters have in common is that no filter can make images of celestial objects brighter because all filters absorb certain wavelengths, making objects darker.Filters are made of plastic or glass with a special dye added, red filters allow only red light to pass through, and so on.
