Total magnification Guías de estudio, Notas de estudios & Resúmenes

Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Condenser lens-Focuses light through the specimen. How do you calculate...
