Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye. There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy.
Microscope A laboratory instrument used to examine objects that are too small to be seen with the naked eye. Microscopy is the science of investigating small objects and structures using a microscope.
There are many types of microscopes and they can be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample on its optical path, detecting photon emissions from a sample, or scanning through a sample. a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the light microscope, which uses lenses to refract visible light that passes through a finely sectioned sample to produce an observable image. Other important types of microscopes are fluorescence microscopes.
HOW AN OPTICAL MICROSCOPE WORKS
The light microscope has long been an indispensable tool in ophthalmic surgery. The first reported use of a binocular microscope in ophthalmology was almost 100 years after Richard Liebreich described his method of magnification in ophthalmic examinations in 1855. This surgical equipment allows ophthalmologists to perform eye surgeries in both the anterior and posterior segment, in any of the most frequent eye surgeries such as cataract, presbyopia or eyestrain, vitreoretin, glaucoma, myopia, hyperopia, astigmatism.
The human eye is an extremely delicate organ, so performing ophthalmic surgery requires the use of high-tech microscopes. Optical microscopes for ophthalmology are designed to provide detailed, high-contrast images of all parts of the human eye. When choosing an ophthalmic microscope it is important to pay attention to the type of optics used.
An ophthalmic surgical microscope can be fixed or adjustable. It can be installed on the ceiling of the operating room or have a mobile base on the floor. Certain models of optical microscopes for ophthalmic surgery have different types of illumination between halogen and LED, and with different types of lenses for high light transmission and with different magnifications, allowing high quality images at low light intensities.
