It is more desirable to increase light when changing to a higher magnification using a compound microscope as the lens require more light. With proper lighting , it is easier to see specimen details as the lens aperture decreases with higher magnification.
early light microscope
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
The amount of light needed increases as one moves to higher magnification with the microscope. This is usually done by opening the light diaphragm.
Total magnification is determined by multiplying the magnification of the ocular lens by that of the objective lens. Compound microscope that uses more than one lens to direct light through a specimen mounted on a glass slide.

it has light limited magnification
The power of a light microscope can be determined by multiplying the magnification power of the eyepiece by the magnification power of the current lens. Ex. (10x) by (40x) results in in a 400x magnification.
The maximum magnification of a light microscope is 2000x. Anything requiring more than 2000x magnification requires an electron microscope.
A compound light microscope is limited to about 2000X magnification.
The Dissecting Light Microscope range of magnification is 20x to 80x. The Compound Light Microscope ranges from 40x to 1000x -40x Scanning -100x Low Power -400x High Power -1000x Oil Immersion
The field of view becomes smaller when magnification increases.
It is more desirable to increase light when changing to a higher magnification using a compound microscope as the lens require more light. With proper lighting , it is easier to see specimen details as the lens aperture decreases with higher magnification.
That's right, an electron microscope can produce more magnification than a compound light microscope.
