középsugár

Középsugár is a Hungarian term that translates to "middle beam" or "central ray." It is most commonly used in the context of photography and optics, referring to the principal ray that passes through the center of a lens or optical system. This ray is important because it travels in a straight line without being refracted or reflected, and it helps define the optical axis of the system. Understanding the behavior of the középsugár is crucial for calculating image formation, magnification, and distortion.

In photography, the középsugár is the imaginary line that extends from the center of the lens to the center of the image sensor. Rays of light that travel along this path are not bent by the lens elements, making them a reference point for optical calculations. Deviations from this central path can lead to various optical aberrations.

The concept of the középsugár also finds application in other optical instruments, such as telescopes and microscopes, where precise image formation is essential. By tracing the path of the középsugár, optical designers can optimize the performance of these devices and ensure accurate representation of the subject. Its theoretical straight-line path simplifies the complex optical calculations involved in designing and analyzing imaging systems.
