47-702-INK 15 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm VIS 0° 425-675nm

The 47-702-INK is a high-quality achromatic doublet lens, boasting a 15 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 immediate use.

The lens is meticulously crafted from two types of Schott glass: N-BK7 and N-SF5. This combination ensures superior optical performance, minimizing chromatic aberration and delivering sharp, clear images. The lens features a doublet geometry, with radii of curvature of 26.81 mm and -23.82 mm for the first surface, and -90.79 mm for the second surface. This geometry contributes to the lens's excellent imaging capabilities.

The 47-702-INK lens has a center thickness of 5 mm and an edge thickness of 5.12 mm, providing robustness and durability. The lens is coated with the EDM VIS-0 STD curve on both the front and back surfaces, enhancing its light transmission capabilities and overall performance in the visible light spectrum.

This lens is a multiplet, meaning it is composed of multiple elements. The multiplet design allows for more complex optical corrections, making the 47-702-INK an ideal choice for a wide range of applications that require high-performance imaging.
