SLB-25B-90P 25.0 mm Dia. x 90.6 mm FL; Double-Convex Lens Uncoated
The SLB-25B-90P is a 25.0 mm diameter double-convex lens with a focal length of 90.6 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a base shape of a circle, with a thickness of 2 mm at the edge and 3.7 mm at the center. The effective focal length (EFL) is 90.6 mm, while the back focal length (BFL) is 89.4 mm. The radii of curvature for the first and second surfaces are 93.42 mm and -93.42 mm, respectively.
This lens is uncoated, offering a cost-effective solution for applications where coating is not required or preferred. However, it's important to note that uncoated lenses may have higher reflectivity and lower transmission compared to coated ones.
