摘　　要：介绍了显微光度计与准显微光度计的区别。光度计视域光栏系统是显微光度计的重要组成部分,它提供了垂直平行入射光束的必要条件,其锁定的测量限区使被测镜质组等反射光不受周围不同物质反射光的干扰影响,保证了镜质组反射率的真实性与正确性。准显微光度计缺失了光度计视域光栏系统,不能提供垂直平行的入射光束,不具有锁定被测镜质组和干酪根不受周围组分光线干扰的功能,所测反射率不具有客观真实性。The difference between microphotometer and quasi-microphotometer was introduced.The visual diaphragm system is the important component of microphotometer,it provides the necessary condition of light beam injected vertically and horizontally,its locked measurement limit area enables the reflectance light of vitrinite to be measured not influenced by interference of reflectance of vitrinite.The trueness and accuracy of the vitrinite reflectivity were ensured.Quasi-microphotometer is lack of microphotometer sight diaphragm system,which can＇t provide light beam vertically and horizontally injected,it has no the function to lock vitrinite to be measured and Kerogen is not interfered by the surrounding splitter line,the reflectivity to be measured has no objective reality.
