The shortest objective lens in a microscope is typically referred to as the scanning lens.

When using a 4x objective lens on a microscope, the total magnification is calculated by multiplying the objective lens magnification by the eyepiece magnification. If the eyepiece (ocular) lens is typically 10x, the total magnification would be 4x (objective) × 10x (eyepiece) = 40x. Therefore, when scanning with a 4x objective, the total magnification will be 40x.
Try it any other way and you'll see. The scanning objective has the largest field of view, the greatest depth of field, and the greatest working distance. It is the most forgiving objective. It is the easiest to find the specimen and focus on it.
The scanning power objective relates to the objective lens. Most microscopes provide two or more objective lenses to give a choice of magnification power. Some also include an oil immersion lens for even greater magnification.
The medium power scanning objective in a microscope typically has a magnification of around 20x to 40x. It is used to locate and focus on the specimen at a lower magnification before switching to higher magnification objectives for detailed observation.
The low power objective lens on a microscope is also known as the scanning lens.
The lowest power of a microscope is typically 4x, known as the scanning objective lens.
Yes, the magnification of the scanning objective is typically 4x. This low magnification is used for quickly locating specimens on a slide and provides a broad field of view. It allows for easier navigation before switching to higher magnification objectives for detailed observation.
