45-421 6.25 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-25mm MgF2 400-700nm
The 45-421 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 6.25 mm, is designed for use in the visible spectrum, specifically between 400-700 nm.
The lens is a multiplet, composed of two distinct materials: N-BAF10 and N-SF10, both from Schott. This combination ensures superior optical performance, minimizing chromatic aberration and distortion. The lens has an effective focal length (EFL) of -25 mm, making it suitable for a wide range of optical applications.
The lens's geometry is meticulously designed, with an edge thickness of 3.27 mm and a center thickness of 1 mm. The lens also features an inner radius of 0 mm and an outer radius of 0 mm, contributing to its compact and efficient design.
The 45-421 lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating enhances the lens's durability and optical performance, providing a broadband anti-reflection coating that is optimized for the visible spectrum.
The lens is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
