Method for measuring nitrogen concentration of diamond and device for measuring nitrogen concentration of diamond

A method for measuring the nitrogen concentration of diamond includes a first step, a second step, and a third step. In the first step, diamond is disposed inside the integrating sphere. In the second step, visible light is incident into the interior of the integrating sphere, and visible light reflected by the inner surface of the integrating sphere and transmitted or reflected by the diamond disposed in the interior of the integrating sphere is received. In the third step, the nitrogen concentration of the diamond is calculated on the basis of the received visible light data and the mass of the diamond. 一种金刚石的氮浓度的测定方法，其具有第一工序、第二工序和第三工序。在第一工序中，在积分球的内部配置金刚石。在第二工序中，向积分球的内部射入可见光，接收在积分球的内表面反射并且在配置于积分球的内部的金刚石透射或反射的可见光。在第三工序中，基于所接收的可见光的数据以及金刚石的质量，计算金刚石的氮浓度。
