Microscope objective lenses have a magnification power that determines the level of detail visible. They also have numerical aperture (NA), which affects resolution and light-gathering ability. The lens design impacts factors like working distance, field of view, and depth of focus.
The arrow would likely point to the cylinder lens, which is the objective lens of the microscope. This lens is responsible for magnifying the specimen being observed.
The magnification of the objective lens is 10x. The magnification of the scanning lens is 4x. Therefore if you are viewing an object under scanning power, the total magnification is 40x.
The focusing knobs are used to regulate the low power objectives on a microscope. These knobs help adjust the distance between the specimen and the objective lens to bring it into focus. By turning the focusing knobs, you can achieve a clear image when using low power objectives.
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
To change the magnification lens on a microscope, first, ensure that the microscope is turned off. Then, gently unscrew or detach the existing lens from the microscope. Carefully insert the new lens in its place and secure it in position. Finally, test the new lens by turning on the microscope and adjusting the focus as needed.

A monocular microscope typically has one main objective lens.
The arrow would likely point to the cylinder lens, which is the objective lens of the microscope. This lens is responsible for magnifying the specimen being observed.
The objective lens on a microscope is responsible for magnifying the specimen being observed. It gathers light rays from the specimen and focuses them to produce a magnified image. By changing objectives, you can adjust the level of magnification on the microscope.
A microscope typically has three main objectives: low-power, high-power, and oil-immersion objectives. Each objective lens magnifies the specimen at a different level, allowing for a range of magnification options.
To determine the total magnification of a microscope you multiply the magnification power of the objectives lens (indicated as x10) by that of the eye piece.
The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
A high power objective in a microscope is a lens that provides high magnification of the specimen being viewed. It typically magnifies the image by 40x to 100x, allowing for detailed observation of fine structures. High power objectives are used for examining smaller details and are typically used after lower magnification objectives.
The magnification of the objective lens is 10x. The magnification of the scanning lens is 4x. Therefore if you are viewing an object under scanning power, the total magnification is 40x.
To clean microscope objectives, a lint-free cloth or lens tissue is typically used, often moistened with lens cleaning solution or distilled water. It's important to avoid using paper towels or rough materials that can scratch the lens. Additionally, gentle circular motions should be employed to remove debris without damaging the optical surfaces. Always ensure the objectives are dry and free from residue after cleaning.
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.
The focusing knobs are used to regulate the low power objectives on a microscope. These knobs help adjust the distance between the specimen and the objective lens to bring it into focus. By turning the focusing knobs, you can achieve a clear image when using low power objectives.
