How do light microscopes work
WebMar 12, 2024 · The optical or light microscope uses visible light transmitted through, refracted around, or reflected from a specimen. The aperture of a microscope determines its resolving power. Resolution is the ability of a microscope to keep all specific details of the object intact in the image. Hence, all microscopes, based on the technique being used ... WebMay 2, 2012 · A hint for practical use: the eye has to be placed a short distance above the microscope. Technically speaking, the pupil of our eye has to be located at the same place as the exit pupil of the microscope. This exit pupil can be easily seen when the light intensity of the microscope illumination is increased.
