LA1085 N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=30.0 mm Uncoated

The LA1085 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 18.0 mm, is designed for use in a wide range of optical systems, offering a focal length of 30.0 mm.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as BK7, is widely used in optical systems due to its low dispersion and high transmission in the visible spectrum. The LA1085 lens, in particular, is designed for use at a wavelength of 587.6 nm.

The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The radius of curvature of the convex side is 15.5 mm, and the lens has a center thickness of 4.7 mm and an edge thickness of 1.8 mm. The back focal length (BFL) of the lens is 26.8 mm, and the effective focal length (EFL) is 30.0 mm.

Notably, this lens is uncoated. While coatings can be applied to enhance the performance of optical components, such as by reducing reflection or increasing transmission, this lens is designed to function effectively without them. This makes it a cost-effective choice for many applications.
