L-BCX124 25 mm Dia. Double-Convex Lens; EFL=400mm Uncoated
The L-BCX124 is a 25 mm diameter double-convex lens, sourced from the reputable optical vendor, Ross Optical. This lens is a spherical type, specifically a convex-convex lens, and features a base shape of a circle. The lens's geometry is meticulously designed with a thickness of 1.5 mm at the edge and 1.9 mm at the center, providing a balanced and robust structure.
The effective focal length (EFL) of this lens is 400mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 413.12, while the second radius (R2) is -413.12, indicating the double-convex nature of the lens. The inner and outer radii are both zero, suggesting a symmetrical design.
This lens is made from n-bk7 Schott material, a high-quality optical glass known for its excellent optical properties. The wavelength for this lens is 587.6 nm, which is within the visible light spectrum. The lens is uncoated, offering a clear and naked optical surface.
