Optics - Lenses: FA12499_LXP-D Application Field and Working Principle

Optics is the branch of physics that deals with the action and behavior of light, including its properties, interactions, and production. One of the main components of optics is lenses, which are transparent mediums, typically of glass or plastic, that have curved surfaces that converge or diverge light rays, allowing for the image formation of an object or to alter the direction of light transmitting through the lens. The specific type of lens examined in this paper is the FA12499_LXP-D lens, an available model manufactured by Sankyo Measurement Corporation. This article will discuss the application field and working principle of the FA12499_LXP-D lens.The FA12499_LXP-D lens is a general-purpose lenses designed for infrared measuring applications in NIR (near infrared) and SWIR (shortwave infrared) wavelengths. It is a focal length system that uses reflective and refractive parts to form a combined system composed of four lenses. The first and fourth lenses are aspheric surface, paraxial and retrofocus, reflecting the light in order to acquire the total optical length. The second and third lenses also possess aspheric surfaces, but are used for custom optical designs. The FA12499_LXP-D lens is optimized for use in a variety of measuring systems, including high-precision dimensional measuring systems, displacement measurement systems, and those utilized in sky navigation and guidance systems. It covers a wide range of wavelengths from the NIR and SWIR bands, where both air breakdown and the transmission of standard silica optical lenses are inadequate, allowing for its application in a variety of fields. The working principle of the FA12499_LXP-D lens involves the use of light refraction and reflection. Refraction occurs when light passes through a lens and is bent by the lens shape, allowing for the formation of an image of the object. This is due to the fact that lighter rays spread outwards from the object when they reach the lens, and the curved shape of the lens causes them to be folded inwards at different points, resulting in an image being formed at the focal point of the lens. Reflection, on the other hand, occurs when light is bounced off of a surface. The FA12499_LXP-D lens contains reflective components, which are surfaces that are designed to deflect light, resulting in the reflected light’s intensity being increased. The FA12499_LXP-D lens combines reflection and refraction to obtain the desired focus length and image formation. The aspheric surfaces of the lenses reduce spherical curvature aberrations and astigmatism, allowing for the lens to form a wide-angle, aberration-corrected image when used in measuring systems.To summarize, the FA12499_LXP-D lens is a general-purpose lenses designed for measuring applications in the NIR and SWIR ranges. It is designed to work using refraction and reflection by having aspheric surfaces and reflective components that allow for aberration-corrected image formation. This makes it an optimal solution for a variety of applications such as measuring and navigation systems due to its ability to cover a wide range of wavelengths.
