SLB-40B-100PM 40.0 mm Dia. x 101.0 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-40B-100PM is a high-quality double-convex lens, boasting a diameter of 40.0 mm and a focal length of 101.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical components.
The lens is crafted from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, with a thickness of 2.0 mm at the edge and 5.9 mm at the center. The effective focal length (EFL) is 101.0 mm, while the back focal length (BFL) is 99.0 mm.
The lens features a coating of opt m on both the front and back surfaces, enhancing its performance within the wavelength range of 400-700nm. This coating ensures optimal light transmission and reduces unwanted reflections, making it suitable for a wide range of applications.
The geometry of the lens is spherical, a common choice for its simplicity and versatility. The first radius of curvature (R1) is 103.8 mm, while the second radius (R2) is -103.8 mm, indicating the double-convex nature of the lens. The inner and outer radii are both 0 mm, suggesting a uniform curvature throughout the lens.
