This makes the cells barely, or not at all, visible in a brightfield microscope. When light passes through cells, small phase shifts occur, which are invisible to the human eye. In a phase contrast microscope, these phase shifts are converted into changes in amplitude, which can be observed...
PROBLEM TO BE SOLVED: To make it possible to effectively improve the resolving power without lowering the image contrast and accurately convert the phase distribution of a phase body which is observed through the phase contrast microscope into a contrast. ;SOLUTION: A slit 2 in a ring zone shap...
相衬显微镜(Phasecontrastmicroscope)第一节相衬显微镜(Phase contrast microscope)在光学显微镜的改进过程中,相衬显微镜的制造成功和普遍的应用,是近代显微镜技术中的重要成就。在1935年荷兰学者泽尼克提出了相衬法原理,至1941年由德国蔡司工厂诞生了世界上第一台相衬显微镜。它的产生,使人类的视觉在光学显微镜下又得到...
