SLB-25.4B-40PIR2 25.4 mm Dia. x 41.0 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-25.4B-40PIR2 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 suited for the infrared spectrum, specifically between 750 nm and 1550 nm.

The lens has a diameter of 25.4 mm and a thickness at the edge of 1.9 mm, while the center thickness measures 5.9 mm. The effective focal length (EFL) is 41 mm, and the back focal length (BFL) is 39 mm. The first radius of curvature (R1) is 41.52 mm, and the second radius of curvature (R2) is -41.52 mm. The lens is made of n-bk7 schott material, a common choice for its high refractive index and low dispersion.

The SLB-25.4B-40PIR2 features a double-convex design, which is beneficial for applications requiring a wide field of view and low distortion. The lens is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the infrared spectrum.
