63-702 4 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=6mm VIS 0° 425-675nm

The 63-702 is a high-quality achromatic doublet lens, boasting a 4 mm diameter and an effective focal length 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 through their official website.

The lens is constructed from two types of Schott glass: N-BAF10 and N-SF10. 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 63-702 achieves superior image quality and color correction.

The lens geometry is meticulously designed, with a diameter of 4 mm, a thickness at the edge of 3.19 mm, and a center thickness of 2.8 mm. The lens features three radii of curvature: r1 at 4.24 mm, r2 at -2.6 mm, and r3 at -18.9 mm. These parameters contribute to the lens's overall performance and optical characteristics.

The 63-702 is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's transmission and reduces reflection, thereby improving light transmission and image quality.
