融熔石英抛光片(JGS1 JGS2 Quartz glass)
光学石英玻璃片,能耐高温和高压等优点,是其他光学材料所无法替代的。石英玻璃具有良好的紫外透过性能;可见光和近红外光吸收极低,所以是生产光导纤维的基础材料。热膨胀系数极小,化学稳定性好,气泡、条纹、均匀性、双折射可与一般光学玻璃媲美,它是在恶劣场合下工作优选的光学材料。主要应用于:特种光源,光学仪器,光电子,军工,冶金,半导体,光通讯等领域。它能实验温度:1200度,软化温度为:1730度,具体参数如下:
The Optical quartz glass sheet has the advantages of high temperature and high pressure, which is irreplaceable by other optical materials. Quartz glass has good ultraviolet transmittance performance; Visible and near-infrared light absorption is extremely low, so it is the basic material for the production of optical fibers. The coefficient of thermal expansion is very small, the chemical stability is good, the bubbles, fringes, uniformity, and birefringence are comparable to the general optical glass, and it is the preferred optical material for working in harsh occasions. Mainly used in: special light source, optical instruments, optoelectronics, military industry, metallurgy, semiconductor, optical communication and other fields. It can be tested at 1200 degrees Celsius, softening temperature: 1730 degrees, the specific parameters are as follows:
1.(远紫外光学石英玻璃)对应牌号 JGS1
它是用高纯度氢氧熔化的光学石英玻璃,所以含有大量的羟基(2000ppm),具有优良的透紫外性能,特别是在短波紫外区,其透过性能远远地胜过所有其他玻璃,在185μm处的透过率可达90%,合成石英玻璃在2730nm处具有很强的吸收峰,无颗粒结构。是185—2500mμ波段范围内的优良光学材料。
It is an optical quartz glass(JGS1) with high purity hydrogen and oxygen melting, so it contains a large number of hydroxyl (2000ppm), with excellent ultraviolet transmission performance, especially in the short-wave ultraviolet region, its transmission performance is far better than all other glass, the transmittance at 185μm can reach 90%, synthetic quartz glass at 2730nm has a strong absorption peak,No granular structure.It is an excellent optical material in the range of 185-2500mμ band.
2.(紫外光学石英玻璃)对应牌号 JGS2
石英原料和氢氧焰生产的石英玻璃,含有几十ppm的金属杂质。在2730nm处有吸收峰(羟基含量100-200ppm),有条纹和颗粒结构。它是透过220—2500μm波段范围内的良好材料。
Quartz glass(JGS2) produced by quartz raw materials and hydrogen and oxygen flame contains tens of ppm of metal impurities.There is an absorption peak at 2730nm (hydroxyl content 100-200ppm), with stripes and granular structure.It is a good material for transmission in the 220-2500 μm band range.
