L-BCX241 50.8 mm Dia. Double-Convex Lens; EFL=400mm Uncoated
The L-BCX241 is a double-convex lens with a diameter of 50.8 mm, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high level of optical precision. The lens is uncoated, providing a clear, naked optical surface.
The lens's geometry is meticulously crafted, with an edge thickness of 3 mm and a center thickness of 4.56 mm. The effective focal length (EFL) is 400 mm, making it suitable for applications requiring a longer focal length. The first radius of curvature (R1) is 412.66 mm, while the second radius (R2) is -412.66 mm, indicating the lens's double-convex nature.
The lens is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The wavelength for this lens is 587.6 nm, which is in the green region of the visible light spectrum.
