Technical Field
[0001] The utility model relates to the technical field of optical lens production, in particular to a coating device used for optical lens production. Background Art
[0002] Optical lenses are essential components in machine vision systems, directly impacting image quality and the implementation and effectiveness of algorithms. Based on focal length, optical lenses can be categorized as short-focus, medium-focus, and long-focus; based on field of view, they can be classified as wide-angle, standard, and telephoto. Based on structure, they can be categorized as fixed-aperture, manual-aperture, automatic-aperture, manual-variable-focus, automatic-focus, automatic-aperture motorized-variable-focus, and motorized (variable aperture, focal length, and focus) lenses. During the optical lens production process, lenses require coating. Lens coating involves applying a very thin, transparent film to the lens surface to reduce light reflection, increase transmittance, provide UV protection, and minimize flare and ghosting. Different coating colors also result in different image color balances. Furthermore, coating can delay lens aging and discoloration, leading to the development of a coating device for optical lens production. Utility Model Content
