62-484-INK 12.5 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-15mm VIS 0° 425-675nm

The 62-484-INK is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the visible light spectrum, specifically between 425 and 675 nanometers.

The lens features an effective focal length (EFL) of -15mm, making it suitable for a wide range of optical applications. The base shape of the lens is circular, and it is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott. This combination of materials helps to minimize chromatic aberration, a common issue in optical systems.

The lens has a thickness of 8.04mm at the edge and 2mm at the center. The center thickness increases to 4mm when considering the anti-reflection coating, which is standard for this lens. The curvature of the lens is defined by three radii: r1=-10.62, r2=8.63, and r3=81.12.

The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating helps to reduce reflections and increase transmission, enhancing the overall performance of the lens.
