focal jm

Focus: In physics, it refers to the convergence point of parallel light rays after being refracted by a lens or reflected by a curved mirror. In photography, when an infinitely distant parallel light enters the camera lens, the point where the light is refracted to the lens 'main axis is the focal point of the lens. This is also the clearest point of the scene captured by the lens. It can be composed of the main focal point and many secondary focal points. Focus Plane: It is the general term for the first focal plane and the second focal plane. The plane that passes through the first focal point (front focal point or object focal point) and is vertical to the main optical axis of the system is called the first focal plane (also known as the front focal plane or object focal plane), and the plane that passes through the second focal point (back focal point or image focal point) and is vertical to the main optical axis of the system is called the second focal plane (also known as the back focal plane or image focal plane). According to the principle of lens imaging, there was always a clear position on the film or sensor of a camera. The plane formed by countless such clear points was the focal plane, and the place where the sensor was installed in the camera was at the focal plane. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The focal length of an objective lens is an important factor in an optical system. There were many methods to measure the focal length of an objective lens. The fixed-focal length collimator method had a large measurement range and high accuracy. The relative error was generally less than 1%. It was a commonly used measurement method. In a telescope, the multiplying power was equal to the focal length of the objective lens divided by the focal length of the eyepieces. In terms of aperture, the F value was the ratio of the focal length of the objective lens (f) to the perimeter of the entrance pupil (D). Different types of telescopes or instruments had different focal length values of the objective lens. For example, the focal length of an astronomical telescope was 400mm, and the focal length of the objective lens of the ZWJ - 851 Collimator was 200mm. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
