45-409 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=80mm MgF2 400-700nm
The 45-409 is a high-quality achromatic doublet lens, 12.5 mm in diameter, with an effective focal length of 80mm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase on their website.
The lens is designed with a multilayered coating, specifically an edm mgf2 std curve, on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700nm, making it suitable for a wide range of optical applications.
The lens's geometry is intricately designed with a range of radii and thicknesses to ensure optimal performance. The inner and outer radii are 0, while the edge thickness is 3.12mm. The center thickness is 2.1mm, and the center a thickness is 1.6mm. The lens's first radius (r1) is 49.62mm, and the second radius (r2) is -35.73mm. The third radius (r3) is -103.22mm.
The lens is composed of two types of materials, N-BK7 Schott and N-SF5 Schott, which are renowned for their optical properties. The combination of these materials and the precise geometry of the lens contribute to its achromatic properties, minimizing chromatic aberration and ensuring high-quality imaging.
