In the machine vision inspection system, the industrial lens is an important optical component, which directly affects the imaging quality. There are various types of industrial lenses on the market, and many aspects need to be considered when selecting models. Pomeas double-rail motorized zoom lens can realize high-precision and high-efficiency inspection, and meet different applications of visual inspection.
The advantages of the guide rail electric zoom lens
1. It can solve the limitation of zoom stuck and zoom times
The traditional automatic zoom lens is limited by the design of the motion mode. During the zoom process, scratching the inner wall of the lens barrel causes the structure to loosen, and the lens is easy to get stuck in the lens barrel during the zoom process. This kind of friction that can easily cause damage cannot be solved by simply changing the material of the lens barrel, which results in extremely limited use of the lens, high marginal cost, and narrow threshold range.
The guide rail electric zoom lens adopts the linear guide motion mode, which reduces the friction loss on the inner wall of the lens barrel during the zoom process and improves the service life of the lens. The guide rail electric zoom lens can achieve more than ten million times of zoom, and the possibility of the zoom structure getting stuck is greatly reduced.
2. Solve the center offset
The center offset is one of the "complications" caused by the loss of the inner wall of the lens barrel. When the gap between the slider and the lens barrel becomes larger, the lens will tilt during the sliding process, and the center point will be shifted to the surrounding. Under the linear guide motion mode, the friction between the slider and the lens barrel is small, the hidden danger of lens tilt is eliminated, and the center point is more stable.
3. Eliminate stray light
Stray light is a "sequel" of wear on the inner wall of the lens. Friction will cause the surface of the object to become smooth. When the lens is imaging the object, the internal structure reflects light, which will directly affect the imaging effect. Linear guide mode can directly eliminate the influence of stray light on imaging.
The guide rail electric zoom lens also has the advantages of high contrast, more accurate zoom, and smaller magnification error, and can be used in precision testing fields such as LED core boards, ITO films, semiconductors, and collimators.
