A microscope is an optical instrument that is used to observe very small objects, and is an indispensable tool in modern science with telescopes.

When observing a sample using a microscope, it is necessary to irradiate with appropriate light. At this time, the light source unit that emits the light appropriately irradiates the sample, and the light is appropriately incident on the lens, so that observation is performed.
