SLB-25B-40PIR1 25.0 mm Dia. x 41.0 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-25B-40PIR1 is a 25.0 mm diameter, double-convex lens with a focal length of 41.0 mm, sourced from OptoSigma. This lens is made from 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 double-convex geometry, with radii of curvature of 41.52 mm for both the front and back surfaces. This geometry, combined with the lens's thickness at the edge (2.0 mm) and center (5.9 mm), contributes to a back focal length of 39.0 mm and an effective focal length of 41.0 mm. The lens's shape is spherical, ensuring a consistent curvature across the entire surface.

The SLB-25B-40PIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 633 and 1064 nm. The coating reduces surface reflections, improving transmission and overall image quality.
