Work Step by Step
The following are the types of microscopes and their descriptions:
Phase-contrast - Uses visible light, but causes some light rays to strike the specimen out of phase with each other;
Dark-field- Uses visible light rays but causes them to reflect off specimen at an angle;
Bright-field- Uses visible light only, with light passing directly through specimen;
Transmission electron- Uses electron beam and electromagnetic lenses and is useful for viewing internal structures of cells;
Confocal- Uses laser light to get thin focal level sections through specimen, resulting in 40X greater resolution and less out-of-focus light;
Scanning electron- Uses electron beam instead of light rays and electromagnetic lenses instead of glass lenses and is useful for viewing surface images of specimen;
Fluorescence- Uses UV light to excite molecules to emit light of different wavelengths;
Nomarski- Uses visible light out of phase.
