Machine vision plays an increasingly important role in many areas of life. As the name suggests, this technology enables automatic recognition and interpretation of images within an organized or structured environment. A wide range of lenses, cameras, and other optical components are available to enable the capture of images and the performance of image processing. In this article, we will discuss the application fields and working principles of two machine vision lenses, the 3Z4S-LE and the VS-3514H1.The 3Z4S-LE is an easy-to-use zoom lens comprised of eight optical lenses. It has a magnification of 0.76-7.6x and a focus range of 230mm. With its smooth and silent zoom mechanism, it operates with great accuracy and repeatability. This lens is designed for use with large 1080p and 4K image sensors, and has a built-in trigger mechanism for precise control. Additionally, its built-in open-loop stabilization reduces user interface complexity and improves system accuracy and speed.The VS-3514H1 lens is designed for infrared imaging applications. It is a multi-focal-length lens with a wide field of view of 8.8°–145°. The lens is made with aspherical lenses, and its cold mirror coating ensures excellent image quality. Its inner focusing system provides a continuous focusing range of 0.25–30m with no focus shift. Additionally, its 10-bit resolution ensures excellent imaging results, even in the presence of wide dynamic range.Here, we will discuss the application fields and working principles of these two lenses.The 3Z4S-LE lens is primarily used in the industrial and medical fields, as well as in surveillance applications. With its built-in trigger and stabilization mechanisms, it enables highly accurate image capture, especially in areas with rapid motion or complex lighting. It is particularly well-suited for applications that require precise and repeatable control, such as alignment, pattern recognition, and imaging for long-distance identification. The VS-3514H1 lens, on the other hand, is designed for infrared imaging applications. It is suitable for applications such as thermal mapping, security monitoring, night vision, and machine vision. Its inner focusing mechanism and 10-bit resolution provide excellent image quality, even in situations with objects at varying distances from the camera. The working principle underlying the 3Z4S-LE lens is based on a “zooming” mechanism. This involves the insertion, removal, and repositioning of optically transparent solid plates between the light source and the image sensor. As the plates are inserted and removed, the amount of light reaching the image sensor is adjusted, thus allowing for a continuous zoom effect. Additionally, the lens is equipped with a trigger mechanism that enables the user to manually trigger the zoom effect.The VS-3514H1 lens relies on the principles of refraction and reflection to acquire images. Refraction occurs when light passes through different mediums, such as glass or air, and is changed in its direction of travel. Reflection occurs when light strikes a reflective surface, such as a mirror, at a particular angle and is reflected off the surface into another angle. The inner focusing system of the VS-3514H1 lens takes advantage of these principles to provide continuous focus from 0.25 to 30 meters with no focus shift.To sum up, the 3Z4S-LE and the VS-3514H1 are two important lenses used in machine vision applications. The 3Z4S-LE is mainly used in industrial and medical fields, while the VS-3514H1 is designed for infrared imaging applications. The 3Z4S-LE is based on a zooming mechanism, while the VS-3514H1 works on the principles of refraction and reflection. Both lenses are capable of providing excellent image quality and precision.
