the optical microscope is a type of microscope that uses visibal light and a system of lenses to magnify images of small samples
The body tube of a compound optical microscope contains two lens systems, the objective lens composed of one or several lenses that magnify the image of the object being examined, and the ocular lens at the eyepiece end. The magnification of the microscope depends on the focal lengths of the two lens systems.
water marbles are made from the same material as contact lenses
An optical microscope of any type uses the light passing through glass lenses. A compound microscope is simply one that uses 2 or more lenses in series. The image is formed normally either in the observer's eye or in a camera fitted to the instrument, or in certain types may be projected onto a screen. An electron microscope passes a finely-focussed beam of electrons through the sample, and creates the resulting image on a photographic film or electronic detectors. The instrument is used to resolve objects that are far smaller than are possible with optical microscopes.
Eyepiece is the lens through which we observe the specimen in a microscope. It multiplies and adjusts the magnification of the objective lenses. Sometimes, it even corrects aberrations of the objective lens.
Microfiber Cleaning Cloth for Microscope Lenses
Microscope objective lenses are the lenses that you can select on the microscope to change to field of view and magnification.
The first step to clean a microscope lens is to take some lens cleaning paper that you can find in specialty shops or distributors of laboratory equipment. Alternatively, use certified cotton. Never touch the microscope lens with your fingertips since fingerprints can affect the microscope's visibility.
A compound microscope has multiple lenses
microscope has two lenses to increase its magnification
An optical microscope uses light and one or more lenses to view cells. An optical microscope with two or more lenses is called a compound optical microscope.
The objective lenses on a microscope collects light and brings the specimens into focus.

Robert Hookes microscope had either two or more lenses. a simple microscope has one lens in it.
compound microscope
The monocular has 3 objective lenses but the stereo microscope has only 2 objective lenses
1. Always carry the microscope in an upright position with two hands. One hand should support the base and the other should be on the on the arm. Use lens paper and lens cleaning solution to clean the lenses on the microscope. Paper towel will scratch the lenses. Use a soft cloth to clean other parts of the microscope. Lens cleaning fluid and paper is a must. Do not substitute paper towel, which is far too coarse and will scratch the lenses. Always set your microscope on a clean, flat surface. 5. Always remove slides from the stage and rotate the nosepiece to the lowest power before returning the microscope to its storage area.
