An assessment by microscope (e.g., light, electron, confocal, etc.).

Application of microscope magnification to the study of materials that cannot be properly seen by the unaided eye.

The application of microscope magnification to the study of materials that cannot be properly seen by the unaided eye.

The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.

The use of various technologies to resolve the structure or features of objects too small or fine to naturally be seen by eye.

(microscopic examination) An assessment by microscope.

Microscopy can be done quickly, but accuracy depends on the experience of the microscopist and quality of equipment. Regulations often limit physicians� use of microscopy for diagnostic purposes outside a certified laboratory.
