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.
