The telecentric industrial lens is an optical lens used for industrial production. It is widely used in fields such as machine vision and automated inspection. . Telecentric industrial lenses can be divided into three categories: object-side telecentric lenses, image-side telecentric lenses and bilateral telecentric lenses based on different imaging principles.
The principal ray of the object-direction telecentric industrial lens is parallel to the optical axis. The gathering of the principal rayRwandans SugardaddyThe center is located at infinity on the image side, which serves to eliminate reading errors caused by incorrect focusing on the object side.
The chief ray of the image-side telecentric lens is parallel to the optical axis. The center of the collection of the chief ray is located at infinity on the object side. The characteristic is that the magnification factor is related to the image distance, and the camera distanceRwanda Sugar Daddy is still Rwandans Escort It does not affect the reduction factor at all.
The principle of a bi-telecentric industrial lens is to place a diaphragm in the center of the lens so that the light entering and exiting the lens is Parallel light, other light is blocked by the aperture RW Escorts and cannot reach the imaging chip. Look at each side to determine whether the image is a telecentric lens or an object. Fang Yuanxin lens. The characteristic is that the magnification factor is not affected by the distance of the object or the distance of the camera. It is mainly used in the field of visual measurement and detection.
Telecentric lenses have many advantages, including large depth of field, low distortion, and high resolutionRwandans Sugardaddyetc. In carRwandans Sugardaddy parts, hardware, PCB boards Rwanda Sugar Daddyetc. are widely used for size measurement, but there are various types of telecentric lenses. When choosing telecentric industrial lenses, you need to choose the appropriate focal length and resolution based on actual needs.
