LLNF-3T11-H

Optics is the scientific study of the properties of light and the behaviour of light in different situations. Lenses are used to control how light is focussed or bent, thereby affecting optical focus. The LLNF-3T11-H is an ideal lens for applications requiring high image quality and excellent surface illumination. This article explains the application fields and working principles of the LLNF-3T11-H.

Application fields and characteristics

The LLNF-3T11-H is a line scan lens from the Nikon family of optics products. It is a high-performance, high-quality imaging lens that is suitable for use in a wide range of applications. It is particularly useful in applications requiring high image quality and high surface illumination. It is capable of faithfully reproducing textured images, even in low light. The lens is also designed to be especially small and light, making it easy to use in tight spaces. It has a large area of coverage, from an extremely large 1.5mm to an extremely large 7mm. It also has a wide field of view, from 33.7 degrees to 107.3 degrees depending on the zoom factor. The lens can be used in various applications such as machine vision systems, medical imaging, and scientific imaging.

Working principle

The LLNF-3T11-H utilizes a Nikon proprietary lens design to provide high image quality and illumination. It is a multi-element aspherical lens and is designed to provide excellent image contrast and accuracy. The lens is based on a three-group optical system. The first two groups are made up of a combination of aspherical and spherical lenses. The third group consists of a single lens made of aspherical elements. This provides excellent image quality over a wide focal length range. The lens also features Nikon\'s unique Automatic Focus Compensation (AFC) system, which ensures that the focus remains constant even when the imaging target changes. This is especially useful for applications such as medical imaging where there may be a need to acquire images with differing target sizes.

Conclusion

The LLNF-3T11-H is an ideal lens for applications requiring high image quality and excellent surface illumination. It is a multi-element aspherical lens that provides excellent image contrast and accuracy. It utilizes Nikon\'s unique Automatic Focus Compensation system, ensuring that the focus remains consistent over a wide range of imaging targets. This makes it ideal for applications such as machine vision systems, medical imaging, and scientific imaging.
