SLB-25.4B-100PM 25.4 mm Dia. x 100.6 mm FL; Coated; Double-Convex Lens 400-700nm

The SLB-25.4B-100PM is a high-quality lens from OptoSigma, designed for use in the 400-700nm wavelength range. This lens is a spherical type, specifically a double-convex lens, which means it has two convex surfaces. The base shape is circular, and the lens is made from n-bk7 schott material, a popular choice for its excellent optical properties.

The lens has a diameter of 25.4mm and a thickness at the edge of 1.9mm. The center thickness is 3.5mm, providing a robust structure. The effective focal length (EFL) is 100.6mm, and the radius of curvature for the first surface (R1) is 103.8mm, while the second surface (R2) has a radius of curvature of -103.8mm. The back focal length (BFL) is 99.4mm.

The SLB-25.4B-100PM comes with a coating on both the front and back surfaces. This coating, identified as 'opt m', enhances the lens's performance in its designated wavelength range. The lens's shape is spherical, which is a common choice for its ease of manufacturing and good optical performance.
