冰洲石即光学方解石。因其无色透明并具有较高的双折射率和偏光性能,因此广泛应用于国防工业和特种光学仪器制作业。如制作大屏幕显示设备,电子计算机的折光、偏光器、偏光显微镜中的尼科尔棱镜、偏光仪、光度计、分光光发计、比色计及旋光测糖计等200余种不同的偏光仪器。但目前所产高质量大尺寸冰洲石还远远满足不了国内外市场的需要。在十一届三中全会精神鼓舞下,浙江广大农村为进一步搞活农村经济,村办、乡办企业
Iceland stone is optical calcite. Because of its colorless and transparent and has a high birefringence and polarization properties, it is widely used in national defense industry and special optical instruments manufacturing industry. Such as the production of large-screen display devices, computer refraction, polarizer, polarizing microscope Nichol prism, polarimeter, photometer, spectrophotometer, colorimeter and polarimeter, etc. More than 200 different kinds of polarization instrument. However, the current production of high-quality large-sized iceland stone far can not meet the needs of domestic and foreign markets. Inspired by the spirit of the Third Plenary Session of the 11th Central Committee of the Communist Party of China, in order to further invigorate rural economy, village-run and township-run enterprises
