49-271 3 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=6mm VIS 0° 425-675nm
The 49-271 is a high-quality achromatic doublet lens, boasting a 3 mm diameter and an effective focal length (EFL) of 6 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website.
The lens is meticulously crafted from two distinct materials, N-BAF10 and N-SF10, both from the reputable Schott glass catalog. This combination ensures superior optical performance, minimizing chromatic aberration and delivering sharp, clear images. The lens features a standard anti-reflective coating, denoted as 'edm vis-0 std curve', on both the front and back surfaces, further enhancing its light transmission capabilities.
The lens geometry is intricately designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 2.67 mm. The first radius of curvature (r1) is 4.13 mm, while the second radius (r2) is -2.36 mm, and the third radius (r3) is -21.7 mm. The center thickness of the lens is 1.97 mm, reducing to 1.03 mm at the edge (a).
