63-711 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm

The 63-711 is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length (EFL) of 100mm, specifically designed for the visible light spectrum ranging from 425 to 675nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their website.

The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring excellent optical performance. The N-BK7 glass is used for the first element, while the second element is made of N-SF5 glass. This combination helps to minimize chromatic aberration, a common issue in lenses, particularly when dealing with a wide spectrum of light.

The lens geometry is meticulously designed, with a thickness of 3.7mm at the edge and 2.5mm at the center. The center thickness reduces to 1.5mm at the center a, providing a compact and efficient design. The lens features two radii on each side, R1 and R2 for the first element, and R3 for the second element. These radii are 60.99mm, -43.74mm, and -130.98mm, respectively, contributing to the lens's excellent imaging capabilities.

The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces, enhancing its light transmission capabilities and providing protection against environmental factors. This lens is a multiplet, meaning it consists of multiple elements, which is a common design for high-performance optical systems.
