Concave lenses are used in the eyepieces of microscopes. However, they are not used alone on the eyepiece, but are joined in a concave-convex combination to prevent internal reflections.

The power of the ocular-lens on a microscope?
An ocular lens is the top part of a microscope it is the eyepiece that you look through. The ocular lens is there it magnify whatever if being viewed. It can be different strengths base on the size power of the lens.
How do you find the total magnifying power of a microscope?
MP=(d/L)*(1-(L-l)f) where d would be the distance from the eye to the image without a lens L is the distance from the eye to the new virtual image (with a lens) l is the distance from the eye to the lens this equation only covers a single lens (whereas there tend to be two in a microscope), but that's no worry; use it twice! (i.e treat both lenses as independent sources of the image)
How do you increase the magnification power of a telescope?
You need to rotate the lenses round to get the best magnification then use the wheels on the side to bring it into focus. If this does not meet your requirement's then you need a better microscope.
What do you use to see small objects?

What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
What type of lens does a light microscope use?
Concave
Does a microscope use a concave lens or a convex lens?
Today's microscopes use convex lenses.
The power of the ocular-lens on a microscope?
An ocular lens is the top part of a microscope it is the eyepiece that you look through. The ocular lens is there it magnify whatever if being viewed. It can be different strengths base on the size power of the lens.
What is tyhe function of eypiece in a microscope?
Eyepiece Lens or Ocular Lens is the lens on top. This is use to see the things or objects to observe or to study.
What is the topmost optic in a microscope?
The topmost optic in a microscope is generally the eyepiece or ocular lens. Use the links below to view pictures with descriptive labels.
What is low power objective in a microscope?
A low power objective in a microscope is a Small Lens with Low Magnifying Power. A microscope head with two eyepiece lenses, one for each eye. Generally this term is used in describing a high power (compound) microscope. With a low power microscope we say "stereo" head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye. In the compound microscope with a binocular head, there are two eyepiece lenses but still only one objective lens and you will not get stereo vision. Hope this helps.
How do you use concave lens in a sentence?
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
How can you change of the power of a single-lens microscope?
multipluing lenses

What type of lens does a reflecting telescope use?
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
What is the total magnification if you only use the eyepiece?
it's impossible to just use the eyepiece without an objective lens, but the eyepiece alone is 10x.
How do you find the total magnifying power of a microscope?
