65-553 25 mm Dia. N-BASF64/N-SF66 Achromatic Doublet; EFL=25mm MgF2 400-700nm
The 65-553 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25 mm, is designed for use in the visible light spectrum, specifically between 400-700 nm.
The lens is a multiplet, meaning it is composed of multiple optical elements. The specific configuration includes two types of Schott glass, N-BASF64 and N-SF66, which are carefully arranged to minimize chromatic aberration, a common issue in lens systems.
The lens has an effective focal length (EFL) of 25 mm, making it suitable for a wide range of optical applications. The geometry of the lens is meticulously designed, with an edge thickness of 13.67 mm and a center thickness of 15.33 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 lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and improving transmission in the visible light spectrum.
