SLB-30-80NM 30.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-30-80NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of -80.0 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 made from n-bk7 schott, a high-quality optical glass, and features a Plano-Concave geometry. The lens has an inner radius of 0 and an outer radius of 0, with a thickness at the edge of 4.8 and a thickness at the center of 2.0. The back focal length (bfl) is -81.3, and the effective focal length (efl) is -80.0.
The SLB-30-80NM is coated with Opt M on both the front and back surfaces, enhancing its performance in specific wavelength ranges. This coating helps to reduce reflection and increase transmission, improving the overall efficiency of the optical system.
