一、无应力评定的一般方法在里曾着重叙述了光学发展的意义和任务。不少文章的作者都曾提到:所有不同种类的物镜,其应力状态均应保持在最低限度,尤其在参考文献中通常称为高性能的或定型成类似衍射极限的显微物镜和照相平版印刷用的物镜。它们对其定型设计、结构、工艺、加工各方面都提出高质量要求。当制造偏光显微镜时,这些特殊要求更是必不可少。除对成像质 First, the general method of stress-free assessment has highlighted the significance and tasks of optical development. The authors of many articles have mentioned that all different kinds of objective lenses should have their stress state kept to a minimum, especially in the literature commonly referred to as high-performance microscope objectives or photolithographic plates Printing objective lens. They put forward high quality requirements for all aspects of their design, structure, technology and processing. These special requirements are even more essential when manufacturing polarized light microscopy. In addition to imaging quality
