45-407 5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=7.5mm MgF2 400-700nm
The 45-407 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 5 mm diameter, is designed for use in the visible spectrum, specifically between 400-700nm, making it suitable for a wide range of optical applications.
The lens features a focal length of 7.5mm, indicated by its Effective Focal Length (EFL). This EFL, combined with its diameter, allows for a compact and efficient optical system. The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott, ensuring high-quality optical performance.
The 45-407 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 increasing transmission in the visible spectrum.
The lens's geometry is intricately designed with three radii (r1, r2, r3) and varying thicknesses at the edge, center, and a specific point (thickness edge, thickness center, thickness center a). This design allows for precise control over the lens's optical properties, ensuring optimal performance in its intended application.
