Study Notes

Microscopy

A microscope uses sunlight or artificial light as its source of illumination.
There are two types of microscopes: light microscope (مجهر املجال املشرق) and dark microscope (مجهر املجال املظلم).

Limitations of High Magnification

At high magnification, the refraction of light can cause image distortion.

Components of a Microscope

The condenser (مكثف) collects and focuses light from the illuminator onto the specimen.
The condenser is located beneath the stage.
The objective lens (عدسة موضوعية) is used to adjust the dioptric power.
