NK-X40B Laboratory Biological Microscope

● Biological microscopes are compound microscopes that are primarily used to observe and study organisms and microorganisms.
● Biological microscopes were the earliest type of microscopes to be invented and the most widely used compound microscope today.
● Conventionally, we usually refer to microscopes that include various accessories such as phase contrast, fluorescence, and polarized light etc. as compound microscopes, to distinguish them from stereo microscopes.
● The most basic biological microscope consists of an eyepiece, an objective lens, a microscope stage, and light source. Both the eyepiece and the objective lens are convex lenses. The objective lens first enlarges the object into a real image. The eyepiece then magnifies the real image again into a virtual image, and finally becomes an inverted magnified virtual image on the retina of the human eye.
