47-689 6.25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=10mm VIS 0° 425-675nm
The 47-689 is a high-quality achromatic doublet lens, boasting a 6.25 mm diameter and an effective focal length of 10mm, 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 Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The lens features a sophisticated geometry, with an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 3.06mm. The edge thickness is slightly greater at 3.23mm, providing added durability.
The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces, enhancing its light transmission capabilities and protecting it from environmental factors. The lens is a multiplet, meaning it is composed of multiple elements, which allows it to correct chromatic aberrations and provide superior image quality.
