Classification Of Optical Glass

Edit:Shanghai TaiYang Technology Co.,Ltd      Date:Jul 26, 2017

  Classification of optical glass

  Colorless optical glass

  The optical constant has a specific requirement, with a high visible area, no choice to absorb coloring and so on. According to the size of the Abbe number is divided into the crown and flint glass, all kinds of high and low according to the refractive index is divided into several kinds, according to the size of the order of refraction. Used as a telescope, microscope, camera and other lenses, prisms, mirrors and so on.

  Anti - radiation optical glass

  There is a high absorption capacity for high energy radiation, with high lead glass and CaO-B2O2 system glass, which can prevent gamma rays and X-ray irradiation, which absorbs slow neutrons and thermal neutrons, mainly for nuclear industry , Medical field as a mask and peep window material.

  Radiation - resistant optical glass

  In some γ-ray, X-ray irradiation, the visible area permeability changes less, varieties and grades and colorless optical glass, for the manufacture of high-energy irradiation under the optical instruments and peep window.

  Colored optical glass

  Also known as filter glass. For the UV, visible, infrared specific wavelength selective absorption and permeability, according to the spectral characteristics are divided into selective absorption, cut-off and neutral gray 3; according to the coloring mechanism is divided into ion coloring, metal colloid coloring and sulfur selenium Chemical coloring class 3, mainly used in the manufacture of filters.

  UV and IR optical glass

  In the ultraviolet or infrared band has a specific optical constant and high transmittance, used as UV, infrared optical instruments or as window material.

  Optical quartz glass

  With silica as the main component, with high temperature, low expansion coefficient, high mechanical strength, good chemical properties, for the manufacture of various bands through the special requirements of the prism, lens, window and mirror. In addition, there are for the large-scale integrated circuit manufacturing photomask board, liquid crystal display panel, video disc plate plate glass; light along the magnetic field lines through the glass when the polarization plane rotation of the magneto-optic glass; light in a certain direction by transmission Ultrasonic glass, the occurrence of light diffraction, reflection, convergence or optical frequency shift of sound and light glass.
