The optics industry has been advancing over the years, and many new optical tools and items have been invented. One of the most notable pieces of technology in the field is the 139A-404R lens. This lens is an impressive piece of engineering that offers a number of benefits for those in the optics industry. In this article, we will discuss the application field and working principle of the 139A-404R lens.

The 139A-404R lens is a type of aspheric doublet lens that is designed to focus light on its edges. It is often used in microscopy, imaging, and near-infrared applications. The lens is composed of two glass elements—the positive element and the negative element—which are arranged in an aspheres configuration. The positive element is typically made of SF115 and the negative element is constructed from either N-BK7 or SF11. The combination of these elements creates a high-performance optics system that is capable of delivering images of objects up to 400 times their original size.

Aside from near-infrared applications, the 139A-404R lens is also used in laser scanning, medical imaging, and photolithography. Its design and construction give it excellent chromatic aberration correction, meaning that it delivers accurate color representation. Due to its superior performance, the 139A-404R lens is also highly sought-after in various optical applications, such as optical data storage and LiDAR.

The working principle of the 139A-404R lens is based on the refraction of light when passing through different materials and surfaces. When light is passed through the lens, it will be refracted at the surfaces that make up the two elements of the lens. This refraction changes the angle of the light, causing it to converge at a certain focal point. The focal point of the 139A-404R lens is typically located at the center of its surface. As the light passes through the lens, it is refracted in such a way that it is then focused on the center of its surface.

This refraction also causes light to be dispersed in multiple directions. This divergence occurs when light passes through the edges of the 139A-404R lens. This edge effect helps to create sharper and more detailed images. Additionally, it assists in creating a wide range of contrast levels in the image, making it easier to see and recognize objects.

The 139A-404R lens is an impressive piece of engineering. It is used in a wide range of applications and its design allows for superior chromatic aberration correction. It focuses light on its edges, creating high-quality images that are sharp and detailed. Lastly, its design also ensures that light is dispersed in multiple directions, creating a wide range of contrast levels within the image.
