63-710-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm VIS 0° 425-675nm

The 63-710-INK is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length (EFL) of 50 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 through their official website.

This achromatic doublet lens is meticulously crafted from two types of Schott glass: N-BK7 and N-SF5. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. By combining these materials, the 63-710-INK achieves superior color correction, making it an ideal choice for a wide range of applications.

The lens features a base shape that is circular, with a thickness of 3.89 mm at the edge. The inner and outer radii are 0, indicating a symmetrical design. The first radius of curvature (r1) is 26.22 mm, while the second radius (r2) is -23.95 mm, and the third radius (r3) is -97.55 mm. The center thickness of the lens is 3 mm, ensuring structural integrity and minimal distortion.

The 63-710-INK is coated with EDM Vis-0 std curve on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall image quality.
