IRRADIANCE MEASURING INSTRUMENT FOR MICROSCOPE, AND MICROSCOPE HAVING THE IRRADIANCE MEASURING INSTRUMENT

摘要

An irradiance measuring instrument for a microscope is intended to measure irradiance of light emitted from an objective of the microscope. The irradiance measuring instrument for a microscope includes, in an order where the light emitted from the objective proceeds, an optical system including a single lens that has a nearly flat surface oriented toward the side of the objective and also has positive power, and a photodetector configured to detect the light in order to measure the irradiance of the light on the nearly flat surface.
