Description

Technical Field

[0001] The utility model relates to the technical field of optical detection, in particular to an automatic focusing detection device. Background Technique

[0002] The focal length is a measure of the convergence or divergence of light in an optical system, referring to the distance from the optical center of the lens to the focus where the light converges when parallel light is incident. It is also the distance from the center of the lens to the imaging plane such as the film or CCD in a camera. An optical system with a short focal length has better light-gathering ability than an optical system with a long focal length. Simply put, the focal length is the distance between the focus and the center point of the mirror.
