Manufacturing environments have become increasingly sophisticated and automated to improve the production process and reduce cost.

Machine vision plays a vital role in this process, enabling automated inspection and verification to ensure high quality and accuracy. To do this requires components such as cameras, lenses, and lighting, but the heart of it all is the lens, whose design and type will dictate the overall performance of the machine vision system.

Two different types of lenses commonly found in machine vision applications are the 3Z4S-LE and the VS-MC50-FNO56 lenses. Let’s look at how each lens functions and what kinds of applications they are best suited for.

3Z4S-LE Lenses

The 3Z4S-LE lens series from Fujinon is a range of high-performance analog CCTV lenses with excellent image quality and a wide range of focal lengths. These lenses feature a specialized optical design that utilizes multi element aspherical lens elements and a floating focus construction to provide sharp and clear imaging over the entire image circle. The lenses also feature a manual iris control on select models to help reduce the effects of glare.

The lenses are suitable for many machine vision applications such as inspection, tracking, and high-speed imaging.

VS-MC50-FNO56 Lenses

The VS-MC50-FNO56 lens series from Fujinon is a range of lenses designed for machine vision applications in tight spaces. This range supports up to 6 megapixel cameras and offers a wide range of focal lengths from 12mm to 75mm. The lenses feature aspherical lenses and low dispersion glass to provide excellent image qualities and resolution. Additionally, they feature a dual-mode auto-iris control that allows for more precise and accurate exposures.

This range of lenses is suitable for a variety of machine vision applications such as machine vision lighting control, inspection, tracking, and counting. They are also well suited for applications that require high optical performance in low light or high contrast environments.

Working Principle

The working principle of a machine vision lens is simple. A lens is an optical device that captures and refracts light to form an image. The main components of a lens are the optics and the aperture. The optics are the lens elements that are made of plastic, glasses, or crystals. These elements refract, reflect and filter light and determine the optical characteristics of the lens such as magnification, resolution, and aberration. The aperture or iris is a set of overlapping plates that control the amount of light that passes through the lens.

A machine vision lens generally consists of three lenses: a main lens for taking a low distortion image, a telephoto lens to increase the angle of view, and a wide angle lens to decrease the angle of view. Depending on the application, the imaging system may use multiple lenses, either in a series or in parallel. The imaging system will then use an algorithm to identify the necessary parameters for optimal performance.

Conclusion

The 3Z4S-LE and VS-MC50-FNO56 lens series are two of the most popular lenses for machine vision applications today. Both lens series have a wide range of focal lengths and offer excellent image quality and resolution. The 3Z4S-LE is best suited for applications that require manual control over exposure and the VS-MC50-FNO56 is well suited for low light and high contrast applications.

The working principle of a machine vision lens is the same regardless of brand or model. All lenses refract and reflect light and each lens has its own unique optical characteristics that dictate its performance in different applications. By understanding the principles behind each lens, you can select the lens most suitable for your machine vision application.
