Professional terminology

Far focal optical systems, also known as focal free optical systems. An optical system with a focus located at an infinite distance. The illumination system is an optical system composed of a light source, a collector, a condenser, and an auxiliary lens, used to illuminate objects. The projection optical system is an optical system that images objects onto photosensitive materials. Photocopying system; Lithograph syste is an optical system that accurately images graphics, text, symbols, etc. onto photosensitive materials. In an electron microscope, a device that aligns an electron beam with the optical axis of the electron optical system. In electron microscopy, an electronic optical device that uses an electric or magnetic field to deflect an electron beam. Ultraviolet microscopy is a microscopy technique that utilizes ultraviolet radiation imaging and uses image converters or film to display and record videos. Infrared microscopy is a microscopy that utilizes infrared radiation imaging and uses image converters or film to display and record video recordings. Fluorescence microscopy is the microscopy of imaging objects emitting fluorescence. Phase contrast microscopy is a microscopy technique that increases image contrast by changing the optical path traveled by diffracted light. Polarized light microscopy is a microscopy that uses polarized light to observe the anisotropy of light and determine related parameters
