A1 Compound Microscope
Compound Microscope, also known as high power (high magnification up to 40x~2000x) microscope, or biological microscope, that uses a compound lens system, including the objective lens (typically 4x, 10x, 40x, 100x), compounded by the eyepiece lens (typically 10x) to obtain a high magnification of 40x, 100x, 400x and 1000x. A condenser beneath the working stage focuses the light directly into the sample. Laboratory level compound microscope usually are upgradeable to dark field, polarizing, phase contrast, and fluorescent, DIC function for special specimens view.
Most people think of a biological microscope when they hear the term compound microscope. This is true that a biological microscope is a compound microscope. But there are some other types of compound microscopes as well. A biological microscope may also be referred to as a brightfield or transmitted light microscope.
