SLB-50-90NM 50.0 mm Dia. x -90.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-50-90NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 50.0 mm and a focal length of -90.0 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 geometry. The curvature of the lens is defined by a radius of 46.71 on the planar side, and the lens has a thickness of 10.3 mm at the edge, reducing to 3 mm at the center. The lens's inner and outer radii are both 0, indicating a uniform curvature.
The SLB-50-90NM 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 within the specified wavelength range.
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.
