scanning objective
Total magnification increases when the objective lens is increased because the objective lens magnifies the image before it reaches the eyepiece lens. The eyepiece then further magnifies the image for viewing.

The 'object lens' in a compound microscope is closest to the object being examined.
A microscope uses an objective lens and an eyepiece lens to magnify tiny objects for closer examination. The objective lens gathers light from the specimen and forms an enlarged image, which is further magnified by the eyepiece lens for viewing.
To view the object
The objective lens in a microscope collects and focuses light onto the specimen, producing an enlarged image that can be viewed through the eyepiece. By controlling the magnification and resolution of the image, the objective lens plays a crucial role in determining the quality and clarity of the observed sample.
The main magnifying parts of a microscope are the objective lens and the ocular lens. The objective lens magnifies the specimen being viewed, while the ocular lens further magnifies the image produced by the objective lens. Together, they help to achieve high magnification for detailed observation of microscopic structures.
Objective lens - Primary lens that magnifies the specimen placed on the stage.
The ocular is the upper lens and objective is the lower lens
The function of the eyepiece is to allow us to 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.
low power objective lens
Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
Because during movement of lens there is no slide below objective .
