47-371 25mm Dia. x 125mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-371 is a high-quality Double-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens is characterized by its 25mm diameter and 125mm focal length, making it suitable for a wide range of applications.
The lens is constructed from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The lens features a standard anti-reflection coating on both the front and back surfaces, designed for the visible spectrum (VIS 0deg), which enhances its light transmission capabilities and reduces unwanted reflections.
The lens's geometry is another notable feature. It has a center thickness of 3.5mm and an edge thickness of 2.28mm, providing a robust structure while maintaining a sleek profile. The radii of curvature for the first and second surfaces are 128.65mm and -128.65mm, respectively, which contributes to its double-convex shape. The back focal length (BFL) is 123.84mm, and the effective focal length (EFL) is 125mm.
This lens is designed to operate within the wavelength range of 425-675nm, making it suitable for a wide range of applications within this spectrum. The 47-371 is a reliable and versatile option for those seeking a high-performance Double-Convex Lens.
