Its design is simple and can be manufactured without difficult. The result obtained is reliable and can be checked readily. This spindle stage possesses the advantages over the extinetion curve method, conoseope method-and a number of computational approachs based on one-axis spindle stage of being simpler to operate and of providing more accurate results. One further advantage of this apparatus over the spindle modified by N.N.Roy is such that measurement, can be made over wide range of angle (35°--87°)between optieal axis plane and the needle axis. Measured mineral can be removed for X-ray structural analysis and electron microprobe analysis if necessary. It can also be used as a oneaxis spindle stage or the variable axis spindle stage proposed by H. Villarroal et at.Temperature-variation apparatus can be attached to it for single, and double variable oil immersion methods.展开更多
