The three objective lenses are typically attached to a rotating nosepiece on a microscope. The nosepiece allows for easy selection of the desired magnification by rotating the lenses into position above the specimen. This configuration enhances the versatility and efficiency of the microscope during observation.
Used in conjunction with the eyepiece lens, the objective lens is what gives an optical microscope its ability to produce magnified images. There are normally three to four objective lenses on microscopes, ranging from 4X to 100X magnification, where the stronger lenses are larger. When coupled with the eyepiece lens, the magnification of a microscope ranges from 40X-1000X, though special conditions are required to achieve a sharp image at 1000X magnification.
The root stem of the word 'stereo' is 'stere' which is New Latin and from the Greek meaning solid, or three dimensional. Because a stereo microscope uses two eyepieces to look down two separate objective lenses, it renders a three dimensional view of the specimen to the viewer.
first you turn magnification lens to lowest setting. second, you remove the slide you were looking at. third, you turn off or unplug the microscope.
Three
The revolving nosepiece is the mechanical part of the microscope that holds the three objectives. It allows you to easily switch between different magnifications by rotating the nosepiece to select the desired objective lens.
three lenses
They are called objective lenses.
Robert Hookes microscope had either two or more lenses. a simple microscope has one lens in it.
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).

A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
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.
the objective is the lens, there is the main ocular lens which you look through and then this leads to the turret. on the turret are 3 (usually) objective lenses which are usually 4x, 10x and 40x. so the objective are three lenses which change the amount of magnification on the microscope. :)

The nose piece holds the odjective lense, rotates, and notes the positive stops for each lens.
A binocular compound microscope is a type of microscope that has two eyepieces (binocular) and uses two sets of lenses to magnify the image of a specimen. This allows for a more comfortable and three-dimensional viewing experience compared to monocular microscopes.
