39-12-5A Optoelectronics

39-12-5A is a type of spherical lens with a short focal length and a large angular field of view. It consists of two thin, positive lenses with a small diameter, usually less than 50 mm. The optical configuration of the lens is symmetric and creates a large field of view with a low optical aberration and distortion.The 39-12-5A lens is widely used in applications such as machine vision, security, microscopy, and industrial inspection. Its wide field of view makes it suitable for capturing images of objects at large distances, making it ideal for applications in surveillance, inspection, and remote sensing.In machine vision applications, the lens is used to capture images of large objects, such as buildings, at close distances. Its wide angle also provides a greater field of view, allowing for more detailed inspection of objects. It can also be used for 3D imaging applications, such as range mapping, to measure the distance of objects and track movement.In microscopy applications, the 39-12-5A lens can be used to capture high-resolution images of small objects. Its short focal length allows for magnification of tiny details, while its wide field of view allows for more precise imaging.The working principle of the 39-12-5A lens is based on the refraction of light. When light passes through a lens, it is bent in accordance with the curved surface of the lens, creating an image. The optical characteristics of the lens determine the size, shape, brightness, and distortion of the image.The 39-12-5A lens is an ideal choice for applications requiring a short focal length and wide field of view. Its low optical aberration and distortion, along with its small size, make it suitable for a variety of uses. By combining its lenses, it can be used to provide detailed images of small and large objects in a variety of applications, making it one of the most versatile lenses available.
