49-284-INK 50 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm
The 49-284-INK is a high-quality achromatic doublet lens, boasting a 50 mm diameter and an effective focal length (EFL) of 100 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, which are carefully selected to minimize chromatic aberration, a common issue in optical systems. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, further enhancing its performance by reducing surface reflections and increasing transmission.
The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 12.55 mm. The center thickness is 13.92 mm, and there is an additional 4 mm thickness at the back surface (center a). The lens's base shape is circular, and its multiplet design ensures superior optical performance.
