LA1422 N-BK7 Plano-Convex Lens; Dia:1 in; f=40.0 mm Uncoated

The LA1422 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch (25.4 mm), is designed for use in a variety of optical systems. The lens features a focal length of 40.0 mm, making it suitable for applications that require a longer focal length.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens's geometry includes a planar surface on one side and a convex surface on the other, with a thickness of 2 mm at the edge and 6.4 mm at the center.

The lens's design includes a spherical shape, which is a common choice for many optical applications due to its ease of manufacturing and good image quality. The lens's effective focal length (EFL) is 40 mm, and its back focal length (BFL) is 35.7 mm. The lens's inner and outer radii are 0, indicating a sharp transition between the lens's surfaces.

Notably, this lens is uncoated. While coatings can be beneficial in reducing reflection and increasing transmission, an uncoated lens can be a suitable choice for applications where such features are not required or where cost is a concern.
