What is the function of an optical microscope?

Answer 1

It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words, its function is to make small objects appear much larger so we can study them in detail.

Answer 2

An optical microscope, also known as a light microscope, uses visible light and a system of lenses to generate magnified images of small objects. Here are its key functions:

Magnification: Optical microscopes magnify objects, allowing us to see details that are not visible to the naked eye. They use a combination of objective lenses and eyepieces to achieve various levels of magnification. Illumination: The microscope illuminates the specimen using visible light. The light source can be from below (transmitted light) or around the objective lens (bright field or dark field illumination). Resolution: Optical microscopes have a limited resolving power due to the wavelength of visible light. They can resolve structures down to approximately 200 nanometers (nm). More advanced techniques, such as phase contrast or differential interference contrast, enhance resolution. Contrast Enhancement: Techniques like phase contrast, polarized light, and fluorescence improve contrast by highlighting specific features within the specimen. Sample Observation: The specimen is placed on a stage and observed through one or two eyepieces. Stereo microscopes provide a 3D effect by showing slightly different images to each eye. Image Capture: A camera attached to the microscope captures images (micrographs) for documentation, analysis, or presentation. Objective Lenses: Compound microscopes have a turret with multiple objective lenses of varying magnifications. These lenses can be rotated into place to zoom in on the specimen

Answer 3

An optical microscope is used to magnify and view small objects or samples that are not visible to the naked eye. It utilizes visible light and lenses to produce a magnified image of the specimen for detailed examination and analysis.
