SLB-15B-90P 15.0 mm Dia. x 90.4 mm FL; Double-Convex Lens Uncoated
The SLB-15B-90P is a 15.0 mm diameter double-convex lens with a focal length of 90.4 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface.
The lens has a base shape of a circle and a spherical geometry. The thickness at the edge is 2 mm, while the center thickness is 2.6 mm. The effective focal length (EFL) is 90.4 mm, and the back focal length (BFL) is 89.6 mm. The first radius of curvature (R1) is 93.42 mm, and the second radius of curvature (R2) is -93.42 mm. The inner radius is 0 mm, and the outer radius is also 0 mm.
This lens is suitable for applications that require a long focal length and a wide field of view. It can be used in various settings, including imaging systems, beam shaping, and laser applications. However, due to its uncoated nature, it may not perform optimally in high-intensity light or harsh environmental conditions.
