光电倍增管显微镜光度仪是鉴定和研究矿物(特别是金属矿物)的必备仪器。由于光电倍增管具有高灵敏度及光电流强度与光照度正比关系良好等特点,因此,光电倍增管法是目前精确测定矿物多种光学性质常数的最佳方法。 光电倍增管显微镜光度仪在国外有多种商品出售,国内也有单位改装和组装此仪器。 作者于178年采用晶体管线路,将光源稳压、直流高压稳压、光电倍增管直流放大组装成一件成型仪器,连接ortholux—Ⅱpol
Photomultiplier tubes Photomicrographs are essential instruments for identifying and studying minerals, especially metallic minerals. Due to the high sensitivity of photomultiplier tube and the good relationship between photocurrent intensity and illuminance, photomultiplier tube method is the best method for accurate determination of a variety of optical properties of minerals. Photomultiplier tube microscope photometer in a variety of foreign products for sale, there are domestic units modified and assembled this instrument. The author of transistor circuits in 178 years, the light source voltage regulator, DC high-voltage regulator, photomultiplier tube DC amplification assembly into a forming instrument, connect ortholux-Ⅱpol
