2154163-3

Optics, part of physics, deals with the behavior and properties of light and related phenomena such as reflection, refraction, and diffraction. Lenses are an important part of optics, and the 2154163-3 model plays an important role in this field. This article will discuss the application field and working principle of the 2154163-3 lens.

Application Field

The 2154163-3 lens is a medium sized lens suitable for use in scientific instruments and other devices. It is most commonly used in the manufacture of microscopes, telescopes, binoculars, and other optical devices used in research, education, and leisure activities. It is also suitable for low end surveillance and security systems. In addition, the 2154163-3 has applications in film and video cameras and in optical components of computers and other electronics.

Working Principle

The 2154163-3 lens is a positive lens with a focal length of about 2 mm. It forms an image of an object, or of distant objects, when placed in front of a camera or other imaging device. Light rays from an object enter the lens and are refracted as they pass through it. This causes the rays from different parts of the object to converge to a single point on the other side of the lens, forming a focused image. The process of forming an image in this way is called refraction or lens focusing.

The 2154163-3 lens consists of two elements, an inner and an outer element, which are made of different materials. The inner element is made of a high index optical glass with a refractive index of 1.85, and the outer element is made of a lower index glass, usually with a refractive index of 1.5. The two elements are joined together by an adhesive, and a black rubber seal is used to prevent dust and moisture from entering.

In order to focus an object or distant objects, the lens must be adjusted properly. This requires adjusting the optical elements (the two lenses described above) to the right positions. The precise adjustment is achieved by moving the lower index glass element until the image is correctly focused. The 2154163-3 lens also has a focusing mechanism which can be adjusted with a knurled knob, allowing the user to make fine adjustments.

Conclusion

The 2154163-3 is a medium sized lens used in a variety of applications ranging from research and educational settings to low end surveillance and security systems. Its optical elements are made of different materials and the focusing is achieved through proper adjustment of the elements. The 2154163-3 lens is an important tool in optics, and its use will only continue to grow as more devices and instruments are developed.
