SLB-20-50NM 20.0 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-20-50NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 20.0 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 made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens has a thickness of 4.0 mm at the edge and 2.0 mm at the center, providing a robust structure while maintaining a sleek profile.
The front and back surfaces of the lens are coated with opt m, a coating that enhances the lens's performance by reducing reflection and increasing transmission. This coating is particularly beneficial when working with high-power light sources or when maintaining image quality is crucial.
The lens's geometry, including an inner radius of 0.0 mm and an outer radius of 0.0 mm, further contributes to its performance. The lens's base shape is circular, making it compatible with a wide range of optical systems.
