Optics - Lenses

Lenses are optics that can focus or disperse light rays by bending them. The term "lens" not only refers to traditional optical lenses, but also includes devices such as mirrors and prisms. Common uses for lenses include magnifying objects, correcting vision, and projecting or collecting light. Lenses are categorized according to shape, focal length, and specialities.

2130232303 Application Field and Working Principle

The 2130232303 model of lens is a spherical double element that is used in multiple optical applications. The lens has a positive focal length and is optimized to produce a sharp image from short to long focus distances. It is commonly used in CCTV, machine vision, medical, and scientific imaging applications, and can also be used for high performance imaging systems.

The 2130232303 lens comprises two spherical elements, one on each side of the iris, separated by an air gap that protects against lens flare. The front element is made of a high refractive index material, typically fluoride glass, and is designed to reduce aberration and increase resolution. The rear element is usually an ordinary optical glass with low dispersive power to correct aberrations and increase light transmission. The two elements act to focus light using refraction, which causes the light entering the lens to bend when passing through each element. Furthermore, the high refractive index of the front element allows for a shorter focal length and a wider field of view. This lens also features Low Dispersion (LD), meaning that the image from the lens is more accurate with less aberration.

Conclusion

The 2130232303 lens is a versatile spherical double element that is suitable for a wide variety of optical applications. It is designed to reduce aberration and increase resolution, resulting in sharper images. The lens features both refraction and Low Dispersion, making it well-suited for high performance imaging systems. In conclusion, the 2130232303 lens is perfect for a variety of optical applications, and is a powerful tool for any imaging system.
