Microscopy
In microscopy, we use an optical instrument known as a microscope to observe and magnify small objects through the lens, enabling the observer to examine the minute structures closely. The word “microscope” comes from the Latin “microscopium,” which is derived from the Greek words “mikros,” meaning “small,” and “skopein,” meaning “to look at.” While the microscope has many parts like an eyepiece, objective lens, aperture, nose piece, stage, and microscopic illuminator, the most important is its lenses. It is through the lenses that the image of the object can be magnified and viewed in detail. Two important parameters in microscopy are magnification and resolution. Magnification measures the total enlargement of the image of an object. The magnification factor varies between 5x-30x. Resolution is the ability of a microscope to differentiate the details of a sample. Microscopy comes in various types, each serving specific purposes. They find applications in research, metallurgy, educational institutions, crime investigation, etc. The different types of microscopy are:
- Optical microscopy
- Electron microscopy
- Scanning probe microscopy
- Ultraviolet microscopy
- Infrared microscopy
- Laser microscopy
- Photoacoustic microscopy
Microscopy
Microscopy is the science of using microscopes to view and magnify objects or specimens that are too small to be seen by the naked eye. It enables the study of structures at the microscopic level, which are typically in the range of nanometers to millimeters. There are several types of microscopy techniques available, including optical microscopy, electron microscopy, scanning probe microscopy, and various advanced imaging methods.
