The SLB-10B-10PIR2 is a spherical lens with a base shape of a circle, sourced from the reputable vendor OptoSigma. This lens is designed for use within the wavelength range of 546.1 nm and is particularly suitable for the infrared spectrum, specifically between 750 nm and 1550 nm.
The lens has a diameter of 10.0 mm and a thickness at the edge of 2.0 mm, while the center thickness measures 4.6 mm. The effective focal length (EFL) of this lens is 10.8 mm, making it a double-convex lens. The first radius of curvature (R1) is 10.38 mm, and the second radius of curvature (R2) is -10.38 mm, which further confirms its double-convex geometry. The back focal length (BFL) is 9.2 mm.
The lens is made of n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens is coated with opt ir2 on both the front and back surfaces, enhancing its performance within the specified wavelength range.
