Product Description

Precision Four-axis CNC machining/ CNC lathe machining Optical parts machining Industrial lens

Optical lens is an indispensable component in machine vision system, which directly affects the quality of imaging and the realization and effect of algorithm. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and telephoto lenses from the focal length; wide-angle, standard, and telephoto lenses from the field of view; Automatic aperture fixed focus lens, manual zoom lens, automatic zoom lens, automatic aperture electric zoom lens, electric three variable (aperture, focal length, focus are all variable) lens, etc.

For cameras, the quality of the lens has always been a key factor affecting the image quality, and digital cameras are of course no exception. Although the CCD resolution of the digital camera is limited, in principle, the optical resolution of the lens is required to be lower; on the other hand, due to the small imaging area of the digital camera (because the digital camera is imaged on the CCD, and the area of the CCD is smaller than that of the CCD) The film of the traditional 35mm camera is much smaller), so the lens needs to ensure a certain image quality. For example, for a certain subject, 200 pixels are required in the horizontal direction to perfectly reproduce its details. If the imaging width is 10mm, a lens with an optical resolution of 20 lines/mm can do the job. If the imaging width is 1mm, the optical resolution of the lens must be above 200 lines/mm. On the other hand, traditional film is more sensitive to ultraviolet rays, and UV mirrors are often required for external shooting, while CCDs are more sensitive to infrared rays. Adding special coatings or external filters to the lens will greatly improve the image quality. The physical aperture of the lens must also be considered, and regardless of its relative aperture, the larger the physical aperture, the greater the luminous flux, the better the digital camera's ability to accept and control light, and the better the image quality.
