The origin of this color can be traced down to the negative lens of the objective and the first ocular lens. Both of them are made of SF3R, a special radiation resistant flint glass (here I have to correct my statement made in another review : The origin of the yellow color is, at least in the EDF, a radiation resistant glass).

这黄色的来源能追踪到物镜的负透镜和第一块目镜，这两个都是SF3R做的，一种特殊的能抗辐射的含铅玻璃（这里我纠正另一个评测中的观点：黄色的来源，至少在EDF中，是抗辐射玻璃）。
