49-284 50 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm
The 49-284 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 reputable optical vendor, Edmund Optics, and is available for purchase on their official 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 front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its light transmission capabilities and overall performance.
The lens geometry is meticulously designed, with a diameter of 50 mm, a thickness at the edge of 12.55 mm, and a center thickness of 13.92 mm. The first and second radii (r1 and r2) are 69.28 mm and -46.95 mm, respectively, while the third radius (r3) is -446.01 mm. The inner and outer radii are both zero, indicating a circular shape.
This lens is a multiplet, meaning it is composed of multiple optical elements. The multiplet design, combined with the high-quality materials and coatings, ensures superior image quality and minimal chromatic aberration.
