The ANB846N Machine Vision Lens is a 2/3 inch fixed-focal lens, described as one of the most compact and lightweight designs on the market. It has a long working distance of 105mm and is capable of a working range from Infinity to 6.3 diopters. This super telephoto lens is effectively designed for those instances where detail is essential and a wide field of view is not.

Uses and Applications
The ANB846N is a specialized lens for a wide range of application fields. Because of its high resolution capability and long working distance, it is often used in the medical field to capture images of distant objects from a microscope, endoscopic cameras, or in telemedicine. Its unique design also makes it ideal for telephoto applications, allowing for the capture of images at great distances with a high level of detail. In addition, it is used in inspection and in-line production applications such as parts verification and code reading, and in image capture for remote PCR test measurement.

Working Principle
When it comes to understanding the working principle of the ANB846N, it all starts with the optics. This lens incorporates an optimized design of 12 elements in 8 groups, including 3 aspherical and 1 ED element. This design enables it to capture sharper, clearer images without aberrations and distortions, even when a wide range of distances is required. It also features the highest MTF values, meaning that the finer details of distant objects can be recorded with accurate clarity. The lens offers a high speed of f2.5, making it possible to capture sharp images even in low-light conditions.

The focusing mechanism of the ANB846N is based on floating aberration control, which allows for quicker and more precise focusing. This is achieved through shifting the optical elements within the lens so that each component is in the ideal position for a quality image. As a result, the lens is able to acquire and maintain a high-level of quality in all situations and ranges. The lens also offers an auto iris with a residual illumination of 0.2lx. This makes it especially advantageous in night-time observation systems.

Lastly, the ANB846N lens also features a mechanical shutter mechanism. This is an electromechanical device that is used to instantly adjust the amount of light that enters the lens. By controlling the shutter speed, it is possible to ensure that the image is not overexposed, creating a clear and vibrant image, even in high-contrast scenes.

Conclusion
The ANB846N Machine Vision Lens is an incredibly versatile instrument that is capable of producing sharp, clear, and detailed images in all applications and distances. It offers a wide range of features, including an optimized design of 12 elements in 8 groups, fast focusing speed, a high speed of f2.5, auto iris, and mechanical shutter. This lens is highly adaptable, making it a suitable choice for medical, inspection, and telephoto applications.
