SLB-40-80NM 40.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-40-80NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 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 crafted from n-bk7 schott, a high-quality optical glass, and features a spherical shape. The geometry of the lens includes an inner radius of 0 and an outer radius of 0, with a thickness at the edge of 7.1 mm and a thickness at the center of 2 mm. The lens's effective focal length (EFL) is -80.0 mm, and the back focal length (BFL) is -81.3 mm.
The SLB-40-80NM is coated with an opt m coating 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.
