Fluorescence Microscope Basics Guide – Principle ＆ Application
A fluorescence microscope is a microscopic optical observation technology that uses light of a specific wavelength to irradiate the object under inspection to produce fluorescence for microscopic inspection, which has a history of more than 100 years. In recent years, due to the wide application of immunofluorescence in the field of medical research and diagnosis, FISH…
What Is Fluorescence Microscopy?
Fluorescence microscopy is a type of optical microscope that uses fluorescence and phosphorescence instead of or in addition to reflection and absorption to study the properties of organic or inorganic substances. Fluorescence is the emission of light from substances that absorb light or other electromagnetic radiation, while phosphorescence is a specific type of photoluminescence related…
