They were invented in 1904 by August Köhler and Moritz von Rohr, scientists working for a microscope-making company. Their creation started from the idea of building a microscope which could achieve higher resolution, so after performing wavelength calculations, they decided to use UV light.
For much of the 20th century, ultraviolet microscopy was widely used because of its potency. With it, it was possible to visualize and study a large number of biological elements and processes that until now had not been described with traditional microscopy. However, phase contrast microscopes were then invented and ultraviolets took a back seat.

The greatest advance in the scientific world came with the arrival of the optical microscope, which is nothing more than an instrument that makes it possible to observe microscopic objects, that is, they cannot be seen with the naked eye by the human eye, this function is thanks to the fact that it has an optical system formed by lenses that increase the image that the user is viewing.
The basis of these equipment is the presence of lenses that change the direction of the light rays, such as converging or diverging, which can produce augmented images. Another fundamental element, without which they could not work, is light, that is why optical microscopes come equipped with a light bulb or lamp at the bottom. There are several types of microscopes, including the compound, which we will discuss below.
