SLB-40B-150PM 40.0 mm Dia. x 150.8 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-40B-150PM is a high-quality double-convex lens, boasting a 40.0 mm diameter and a focal length of 150.8 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical components. The lens is made from n-bk7 schott, a material widely used in optical systems due to its excellent optical properties.
The lens features a base shape of a circle, with a thickness of 2 mm at the edge and 4.6 mm at the center. The effective focal length (EFL) is 150.8 mm, while the back focal length (BFL) is 149.2 mm. The first radius of curvature (R1) is 155.7 mm, and the second radius of curvature (R2) is -155.7 mm, indicating the double-convex nature of the lens.
The SLB-40B-150PM is coated with opt m on both the front and back surfaces, enhancing its performance in the 400-700 nm wavelength range. This coating ensures high transmission and low reflection, making it suitable for various applications, including imaging systems, beam shaping, and laser applications.
