SLB-40-70P 40.0 mm Dia. x 70.0 mm FL; Plano-Convex Lens Uncoated
The SLB-40-70P is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 70.0 mm, sourced from OptoSigma. This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens has a base shape of Circular and a spherical geometry. The thickness at the edge is 2.0 mm, while the center thickness is 8.0 mm. The effective focal length (EFL) is 70.0 mm, and the radius of curvature (R1) is 36.33 mm. The back focal length (BFL) is 64.7 mm, and both the inner and outer radii are 0 mm.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens can be used across a wide range of wavelengths, including 546.1 nm, without the risk of coating damage or degradation.
The SLB-40-70P is currently in stock and available for purchase through the OptoSigma website. With its high-quality materials and precise specifications, this lens is suitable for a variety of optical applications.
