SLB-50-70NM 50.0 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-50-70NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 50.0 mm and a focal length of -70.0 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 spherical shape. The geometry of the lens includes an edge thickness of 13.0 mm and a center thickness of 3.0 mm. The lens's design also incorporates an inner radius of 0 mm and an outer radius of 0 mm.
The SLB-50-70NM 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 and quality of the optical system in which it is used.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
