scanning objective
The objective lens in a microscope is mainly used to magnify an object. In a telescope, the objective lens is mainly used to gather light.
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.
Total magnification is calculated by objective times ocular lens. So if you increase the objective lens is directly related to an increase in magnification.
On a typical light microscope, the low power objective lens will be shorter than the high power objective lens.
The lens with the greatest (positive) curvature. The lens with the highest diopter.
40x
scanning-40x low-100x high-400x
The lens with the smallest magnification has the largest field of view.( usually 4x)
The ocular is the upper lens and objective is the lower lens
low power objective lens
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.
Because during movement of lens there is no slide below objective .

The objective lens 40X(with the blue band) is the high dry lens.
the ocular lens sits higher up, closer to your eye. the objective lens are in the objective tube below the ocular lens
