A light source on a microscope helps make the object that you're looking at easier to see.
It brightens up the view so the object can be seen more clearly and can be more "in focus".
It is used to illuminate the slide so that the image is bright enough to see or photograph.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
Any organic substance or sample thin enough to let light through.
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
Photomicrograph
Natural light. The vast majority of Adams' work is landscape photography.

Without the light source, you wouldn't be able to see your sample very well!
A steady light source used in place of a mirror. it is used to reflect light from an external light source up through the bottom of the stage
IF YOU HAVE A MICROSCOPE THAT DOES NOT HAVE AN INTERNAL LIGHT SOURCE, YOU WILL HAVE TO USE THE EXTERNAL LIGHT SOURCE THAT IS PROVIDED IN THE CABINET WITH THE MICROSCOPE.
Light.
compound and light microscopes are used in some labs compound uses a mirror to reflect and a light gives a light source to it

The Function of a base in a microscope, light microscope that is, is to provide the stage with a light source as well as provide a support for the lens of the Microscope.
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
mirroor
A Scanning Electron Microscope, or SEM, is a type of electron microscope. Its light source is from a beam of high voltage electrons.
