SLB-20-80NM 20.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 400-700nm

The SLB-20-80NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 20.0 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 fabricated from n-bk7 Schott, a popular material in optical systems due to its excellent optical properties. The lens features a plano-concave geometry, with a center thickness of 2.0 mm and an edge thickness of 3.2 mm. This geometry, combined with the lens's material, provides high-quality imaging and light transmission.

The SLB-20-80NM 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.

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.
