Selection method of VST lens in Japan

The setting environment of machine vision system is varied, from the inside of special inspection equipment on factory production line to automatic robots. Shooting objects range from tiny IC chips to cars several meters long. According to different environments, it is very important for the camera to accurately grasp the object, and the choice of lens and light source is very important. VST provides customers with machine vision products that meet their needs. VST lens summarizes the advantages and disadvantages of telecentric lens VS-TC series

VS-TCH series

The main light of VS-TCM series lens is parallel to the optical axis of the lens, and the coaxial incident light source must have high object accuracy and no perspective error. The lens is big and expensive. Macro lens VS-MC series.

VS-LD series is used for close to low-distortion photographic TV-small in size, light in weight and good in earthquake resistance. It is only suitable for a certain WD, and the field of view (magnification) is limited. SV series CCTV lens can focus infinitely, adjust the focal length and adjust the simple field of vision with screws. WD can be adjusted at will, and the price is low, which is suitable for the possible distortion around the large field of view. Variable line scanning lens VS-L series by inch-by-inch method

VS-LTC series is mainly used for line induction with low distortion and small shadow. Good shock resistance, large-size bulky zoom lens VSZ series can change the magnification without changing the working distance and camera position, and can change the focal length at any time as needed, without replacing the lens with large focal length span, which is not as large as the one with close focal length.
