62-487 12.5 mm Dia. N-BK7/N-SF5 Negative Achromatic Doublet; EFL=-35mm VIS 0° 425-675nm

The 62-487 is a high-quality negative achromatic doublet lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 12.5 mm diameter and a focal length of -35 mm, specifically designed for the visible light spectrum, spanning 425-675 nm.

The lens is meticulously crafted from two distinct materials, N-BK7 and N-SF5, both from the reputable Schott glass catalog. This combination ensures superior optical performance, minimizing chromatic aberration and delivering sharp, clear images.

The lens features a robust construction, with a thickness of 4.74 mm at the edge and 2 mm at the center. The inner and outer radii are optimized for optimal light transmission and focus, while the center thickness is a mere 1.56 mm, reducing unnecessary weight and maintaining a compact profile.

Both the front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its light transmission capabilities and providing excellent protection against environmental factors. This lens is ideal for a variety of applications, including imaging systems, beam shaping, and other optical instrumentation.

With its superior materials, precision construction, and versatile coating, the 62-487 negative achromatic doublet lens is a reliable and high-performing choice for your optical needs.
