Product Description:Ultra-violet high-transmitting optical glass refers to an optical glass with the same optical constants and physical and chemical properties as some colorless optical glasses, but the transmittance of ultraviolet and visible light is much higher than that of the general ones. Glass.
An inorganic glassy material that transmits light by refraction, reflection, transmission, or changes the intensity or spectral distribution of light by absorption. Has stable optical properties and high optical uniformity. According to optical characteristics, it is divided into:
1. Colorless optical glass. There are specific requirements for optical constants, and it has the characteristics of high transmission in the visible region and non-selective absorption coloring. According to the Abbe number, it is divided into coronal glass and flint glass, and each type is divided into several types according to the refractive index, and they are arranged in order according to the refractive index. Mostly used as lenses, prisms, mirrors, etc. for telescopes, microscopes, cameras, etc.
2. Anti-radiation optical glass. It has a large absorption capacity for high-energy radiation. There are high-lead glass and CaO-B2O2 system glass. The former can prevent γ-ray and X-ray radiation, and the latter can absorb slow neutrons and thermal neutrons. It is mainly used in the nuclear industry. , medical fields, etc. as shielding and peep window materials.
3. Radiation resistant optical glass. Under certain γ-ray and X-ray irradiation, the transmittance in the visible region changes less, and the variety and grade are the same as the colorless optical glass, which is used to manufacture optical instruments and peep windows under high-energy irradiation.
4. Colored optical glass. Also called filter glass. It has selective absorption and transmission properties for specific wavelengths in the ultraviolet, visible and infrared regions. According to spectral characteristics, it is divided into three types: selective absorption type, cut-off type and neutral gray; There are 3 types of chemical coloring, which are mainly used in the manufacture of optical filters.
5. Ultraviolet and infrared optical glass. It has specific optical constants and high transmittance in the ultraviolet or infrared band, and is used as ultraviolet and infrared optical instruments or as window materials.
6. Optical quartz glass. With silicon dioxide as the main component, it has the characteristics of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. In addition, there are photomasks, liquid crystal display panels, and thin-plate glass for image disc substrates used in the manufacture of large-scale integrated circuits; magneto-optical glass in which the polarization plane rotates when light passes through the glass along the direction of the magnetic lines of force; When the ultrasonic glass is used, the diffraction, reflection, convergence or frequency shift of light occurs in acousto-optic glass, etc.
Product features:
It has high transmission performance in the ultraviolet spectral band, and is a kind of optical glass with very good performance. However, high-purity quartz glass has considerable difficulties in raw material purification and melting temperature.
Application range:
Mainly used in ultraviolet spectrometers, optoelectronic devices, and optical instruments and camera lenses that require particularly high visible light transmittance.
