What are the illuminating parts of a microscope?

Illuminating parts are a mirror and a condenser lens. The light beams from different sources are reflected back by the mirror into the condenser lens, which focuses the light onto the specimen.

What are the mechanical magnifying and illuminating parts of microscope?

Parts of a Microscope

It consists of mainly three parts: Mechanical part – base, c-shaped arm and stage. Magnifying part – objective lens and ocular lens. Illuminating part – sub stage condenser, iris diaphragm, light source.

What is the illumination source for a light microscope?

There are a wide variety of light sources available to illuminate microscopes, both for routine observation and for quantitative digital imaging. A most common light source, because of its low cost and long life, is the 30 to 100 watt tungsten-halogen lamp.

What are the lenses on a microscope called?

The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object. Before purchasing or using a microscope, it is important to know the functions of each part.

What is the purpose of a light source on a microscope?

The illumination system of the standard optical microscope is designed to transmit light through a translucent object for viewing. In a modern microscope it consists of a light source, such as an electric lamp or a light-emitting diode, and a lens system forming the condenser.
