Dual telecentric optical system-based machine vision inspection equipment suitable for industrial applications

Machine vision inspection equipment based on double telecentric optical system suits industrial applications

      With the rapid development of automated inspection technology, the industry's demand for high-precision inspection and measurement has gradually increased. Traditional technical solutions are no longer capable, so the application of machine vision inspection systems and equipment has not improved. Machine inspection equipment based on the double telecentric optical system has performance advantages such as no perspective error, near zero distortion, and high resolution. Therefore, it is fully suitable for industrial applications and is the best solution for high-precision inspection.

      Optical system, as a major pillar of machine vision applications, is one of the indispensable technologies, and the advantages of telecentric optical systems in industry applications are already evident. The so-called telecentric optical system refers to an optical system whose principal rays are parallel to the optical axis of the lens. The light emitted from the object toward the lens and kept parallel to the optical axis, even when it is off-axis, is called the object-side telecentric optical system; the light from the lens toward the image is kept parallel to the optical axis, even outside the axis. , It is called image-side telecentric optical system.

When it comes to telecentric optical systems, telecentric lenses have to be mentioned. Telecentric lenses are high-end machine vision lenses and core components of telecentric optical systems. They can generally be divided into two categories: object-side telecentric lenses and dual Telecentric lens.

The advantage of the object-side telecentric lens is that it does not change the size or position of the object when moving the object surface up and down. When using coaxial lighting. Smaller sizes can be used. The disadvantage is that it is larger than a standard lens when coaxial lighting is not used.

       The advantages of the bi-telecentric lens: zero distortion, no perspective error, especially suitable for high-precision inspection and measurement industry applications; the disadvantage is higher cost.

In the industrial application of machine vision technology, telecentric lens technology is indispensable. It has become a decisive component of precision optical measurement systems. Telecentric Optical System (BTOS) 's new dual-telecentric industrial lens series is an object-side / image-side dual-telecentric lens developed according to the needs of a large number of users. The lens is a key component of various precision measurement systems based on machine vision technology, with almost no distortion in imaging. Not only can you use the aperture and magnification to enhance the natural depth of field, but also unparalleled optical effects of non-telecentric lenses.

Looking at the development of the industry, along with the growing demand for applications in the high-precision inspection and measurement industry, the application of high-performance machine vision bi-telecentric optical inspection systems and equipment will also be further enhanced. The machine vision inspection equipment based on the bi-telecentric optical system has successfully put into industrial application under the way that vision inspection is driven by market demand. An efficient detection method. Greatly improve the quality and performance of precision products, shorten the inspection cycle, and reduce labor costs.
