近年来,国内不少科研单位使用西德莱兹公司产的MPV系列显微光度计来测定试样的反射率、开展矿物研究、煤质分析、炼焦配煤试验等。因为该仪器要求被测样品表面的平整度极高,而传统的将样片以胶泥粘在金属载片上,再用压平机压平的方法,由于胶泥的回弹性,难以保证光片表面垂直于显微镜光轴,从而影响测试精度。莱兹公司生产的调平台虽可 In recent years, many domestic research institutes use the MPV series photometer photometer produced by the West Leeds company to measure the reflectivity of the sample and carry out mineral research, coal quality analysis and coking coal blending test. Because the instrument requires the surface of the measured sample flatness is very high, and the traditional sample stick to the metal carrier with clay, and then flatten the flattening method, due to the resilience of the clay, it is difficult to ensure that the surface of the light perpendicular to the film Microscope optical axis, thus affecting the test accuracy.
