SLB-50.8-400PIR1 50.8 mm Dia. x 400.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-50.8-400PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 50.8 mm and a focal length of 400.0 mm. This lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens features a front and back coating of opt IR1, which is specifically designed for infrared applications, making it suitable for use within the wavelength range of 633-1064nm.
The lens has a thickness of 3 mm at the edge and 4.5 mm at the center, with an effective focal length (EFL) of 400 mm and a back focal length (BFL) of 397 mm. The inner and outer radii are both 0 mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 207.6 mm on the curved side.
This lens is part of the Spherical Lens (Plano-Convex) subtype and has a circular base shape. The item data indicates that it is in stock and available for immediate use.
