OptoSigma presents the SLB-25.4B-100P, a 25.4 mm diameter double-convex lens with a focal length of 100.6 mm. This lens is uncoated and features a base shape of a circle, with a standard spherical geometry.
The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The diameter of the lens is 25.4 mm, with a thickness at the edge of 1.9 mm and a center thickness of 3.5 mm. The effective focal length (EFL) is 100.6 mm, while the back focal length (BFL) is 99.4 mm.
The curvature radii of the lens are R1 = 103.8 mm and R2 = -103.8 mm. The lens is uncoated, offering a clear, unaltered view of the light passing through. The wavelength for this lens is 546.1 nm.
This lens is ideal for applications that require a high-quality, double-convex lens with a long focal length. Its uncoated surface makes it suitable for use in environments where anti-reflection coatings are not necessary. The lens is currently in stock and available for immediate purchase from the OptoSigma website.
