SLB-08B-20P 8.0 mm Dia. x 20.4 mm FL; Double-Convex Lens Uncoated
The SLB-08B-20P is a high-quality double-convex lens, sourced from the reputable vendor OptoSigma. This lens is designed with a spherical shape and a circular base, making it suitable for a wide range of optical applications. The lens is fabricated from the renowned material n-bk7 schott, a borosilicate crown glass known for its excellent optical properties.
The lens boasts a diameter of 8.0 mm and a thickness that varies from 1.5 mm at the edge to 2.3 mm at the center. The effective focal length (EFL) of this lens is 20.4 mm, providing a substantial focal length for various optical systems. The first radius of curvature (R1) is 20.76 mm, while the second radius of curvature (R2) is -20.76 mm, indicating the double-convex nature of the lens. The back focal length (BFL) is 19.6 mm, which is crucial for determining the position of the lens in an optical system.
The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. The wavelength for this lens is 546.1 nm, which is within the visible light spectrum.
