L-BCX118 25 mm Dia. Double-Convex Lens; EFL=125mm Uncoated
The L-BCX118 is a 25 mm diameter double-convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically a convex-convex lens with a circular base shape. It is designed for use in a wide range of optical applications, thanks to its versatile specifications.
The lens has an effective focal length (EFL) of 125mm, making it suitable for applications that require a longer focal length. The geometry of the lens is well-defined, with a thickness of 2mm at the edge and 3.2mm at the center. The radii of curvature for the first and second surfaces are 128.65mm and -128.65mm respectively, indicating a symmetrical design.
The L-BCX118 is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The wavelength for this lens is 587.6nm, which is within the visible light spectrum. Notably, this lens does not come with any coating, which may affect its performance in certain applications. However, its uncoated nature allows for customization, depending on the user's specific requirements.
