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.
