LA1951 N-BK7 Plano-Convex Lens; Dia:1 in; f=25.4 mm Uncoated

The LA1951 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 1 inch and a focal length of 25.4 mm, is designed for use in a wide range of optical systems, including imaging, beam shaping, and laser applications.

The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for applications that require high image quality and color correction. The Plano-Convex design of the lens, with a flat front surface and a curved back surface, allows for efficient light collection and focusing.

The geometry of the LA1951 lens includes a diameter of 25.4 mm, a thickness at the edge of 1.8 mm, and a thickness at the center of 11.7 mm. The effective focal length (EFL) is 25.4 mm, and the radius of curvature of the curved surface is 13.1 mm. The back focal length (BFL) is 17.6 mm. The lens does not have any coating, which means it is uncoated. However, it can be customized with various coatings to enhance its performance in specific applications.
