SLB-30-35NM 30.0 mm Dia. x -35.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-30-35NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of -35.0 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 popular material in the optical industry due to its excellent optical properties. The lens features a concave shape with an inner radius of 0 and an outer radius of 0. The center thickness of the lens is 2mm, while the edge thickness is 9.9mm, providing a robust structure for various applications.
The SLB-30-35NM is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The item data also provides the Effective Focal Length (EFL) of the lens, which is -36.3mm, and the Radius of Curvature (R1) of -18.17mm. These specifications are crucial in determining the lens's performance within an optical system.
