SLB-50-80NM 50.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-50-80NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 50.0 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 made from n-BK7 Schott, a high-quality optical glass, and features a Plano-Concave geometry. The lens's inner radius is 0mm, while the outer radius is also 0mm, indicating a uniform curvature. The thickness at the edge of the lens is 11.4mm, and it decreases to 3mm at the center, providing a sleek and compact design.
The SLB-50-80NM is coated with Opt M on both the front and back surfaces, enhancing its performance and durability. This coating reduces reflection and increases transmission, making the lens more efficient in transmitting light.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website, which is provided in the item data.
