SLB-25-50NM 25.0 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-25-50NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 25.0 mm and a focal length of -50.0 mm. This lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is fabricated from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 5.2mm and a thickness at the center of 2mm. The back focal length (bfl) is -51.3mm, and the radius of curvature (r1) is -25.95mm.
The SLB-25-50NM is coated with Opt M on both the front and back surfaces, enhancing its performance in specific wavelength ranges. This coating helps reduce reflection and increase transmission, thereby improving the overall efficiency of the optical system in which the lens is used.
