LA1560 N-BK7 Plano-Convex Lens; Dia:0.5 in; f=25.0 mm Uncoated

The LA1560 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 0.5 inches and a focal length of 25.0 mm, is designed for use in a wide range of optical systems.

The lens is made of 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 an ideal choice for many applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide high-quality performance, especially in applications where anti-reflection coatings are not required.

The geometry of the lens is spherical, with a planar surface on one side and a convex surface on the other. The planar surface has a radius of curvature of 12.9 mm, while the convex surface has a radius of 22.6 mm. The lens has a thickness of 1.8 mm at the edge and 3.5 mm at the center. The effective focal length (EFL) of the lens is 25.0 mm.

This lens is suitable for use in monochromatic applications at a wavelength of 587.6 nm. It is circular in shape, making it compatible with a wide range of optical systems. The lens is currently in stock, according to the vendor's website, ensuring quick delivery for your optical project needs.
