Microscope system of ICSI for insemination and microscope observation method

摘要

A transmission illumination optical system having a light source (11), condenser lens (13), the microscope system is 40 times less than 20 times or more differential interference viewing method and observation by one can be at least one of the modulation contrast viewing method and a dry objective lens of the second 100-fold less than 60 times or more the dry objective lens of the first and (15a), observed by differential interference observation methods is possible and (15b), the first objective lens ( and is characterized in that it is switchable available the second objective lens and (15b) and 15a).
