LA1472 N-BK7 Plano-Convex Lens; Dia:9.0 mm; f=20.0 mm Uncoated

The LA1472 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 9.0 mm, is designed to focus light at a focal length of 20.0 mm, making it ideal for a wide range of optical applications.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it a popular choice for many optical systems. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The geometry of the lens is spherical, with a radius of curvature of 10.3 mm for the convex surface. The thickness of the lens varies from 1.5 mm at the edge to 2.5 mm at the center. The back focal length is 18.3 mm, and the effective focal length is 20.0 mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.

This lens is designed to work with light of a wavelength of 587.6 nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is used with. Therefore, it is crucial to ensure that this lens is suitable for your specific application.

In conclusion, the LA1472 N-BK7 Plano-Convex Lens is a versatile and reliable optical component, suitable for a wide range of applications. Its high-quality construction and excellent optical properties make it a valuable addition to any optical system.
