Microscope.
A compound microscope uses both an objective lens and an eyepiece lens. The objective lens is located near the specimen and provides initial magnification, while the eyepiece lens further magnifies the image for viewing. This combination allows for detailed observation of small objects and biological specimens.
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
The lens you look through in a telescope, binocular, or microscope is called the eyepiece. It is the lens closest to your eye that magnifies the image produced by the objective lens.
The eyepiece of a reflecting telescope typically contains a convex lens. This lens helps magnify the focused light that has been reflected off the primary mirror, allowing the observer to see a magnified image of the object being observed.

ocular lens
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
A compound microscope is made up of two or more lenses in its optical system. The objective lens magnifies the specimen, and the eyepiece lens further magnifies the image produced by the objective lens. This combination of lenses allows for higher magnification and resolution compared to simple microscopes.

A light microscope uses a combination of convex lenses, including objective lenses and eyepiece lenses, to magnify and focus light passing through the specimen. The objective lens is closer to the specimen and creates the initial magnified image, while the eyepiece lens further magnifies the image for viewing by the observer.
A compound microscope uses a combination of two lenses - the objective lens and the eyepiece lens. The objective lens captures and magnifies the image of the specimen, which is then further magnified by the eyepiece lens. By working together, these lenses increase the size of the image produced, allowing for greater magnification and visualization of tiny details on the specimen.
The ocular lens are 10x magnification. Objective lens are 4x, 10x, 40x, 100x magnification. So once an objective lens is selected, the total magnification would be given by its product with the 10x magnification of the ocular lens. For example, if objective lens selected is 40x, total magnification would be: (10x)(40x)=400x total.
Ocular lens is a type of eyepiece that is attached to a variety of optical devices such as telescopes and microscopes.
The compound light microscope gets its name from its ability to use multiple lenses (compound) and light to magnify and observe objects. This type of microscope typically has two sets of lenses for magnification - the ocular lens (eyepiece) and the objective lens.
The eyepiece of a reflecting telescope typically contains a convex lens. This lens helps magnify the focused light that has been reflected off the primary mirror, allowing the observer to see a magnified image of the object being observed.
A compound microscope uses a series of magnifying lenses to observe small objects. This type of microscope typically consists of an eyepiece lens and objective lenses to achieve increasing levels of magnification.
