47-737-INK 40 mm Dia. N-SK11/N-SF5 Achromatic Doublet; EFL=60mm VIS 0° 425-675nm

The 47-737-INK is a high-quality Achromatic Doublet lens, boasting a 40 mm diameter and effective focal length of 60 mm, specifically designed for the visible spectrum range of 425-675 nm. Sourced from the renowned optical vendor Edmund Optics, this lens is a multiplet, featuring a complex geometry that ensures superior performance.

The lens is constructed from two types of Schott glass, N-SK11 and N-SF5, each with its unique optical properties that contribute to the lens's overall performance. The front and back surfaces of the lens are coated with EDm vis-0 std curve, a proprietary coating developed by Edmund Optics, further enhancing its light transmission capabilities and durability.

The lens's geometry is intricately designed, with a diameter of 40 mm, a thickness at the edge of 10.03 mm, and a center thickness of 14.46 mm. The lens's inner and outer radii are 0, indicating a circular shape. The lens's first and second radii (r1 and r2) are 37.33 mm and -31.54 mm, respectively, while the third radius (r3) is -124.51 mm. These radii contribute to the lens's complex curvature, which is essential for its achromatic properties.

The lens's thickness at the center is 14.46 mm, while its thickness at the center 'a' is 3 mm. The lens's shape is a multiplet, indicating a compound lens made up of multiple elements. This design allows for the correction of various optical aberrations, ensuring high-quality imaging.

The lens is available for purchase through the Edmund Optics website, where it is listed as in stock. The website also provides a direct link to the product page for easy access and purchase.
