65-551 15 mm Dia. N-BASF64/N-SF66 Achromatic Doublet; EFL=15mm MgF2 400-700nm
The 65-551 is a high-quality Achromatic Doublet lens, 15 mm in diameter, and manufactured by Edmund Optics. This lens is designed for use in the visible spectrum, specifically between 400-700nm, and features a standard MgF2 coating on both the front and back surfaces.
The lens is a multiplet, meaning it is composed of multiple optical elements. The first element has a radius of curvature (R1) of 11.39, while the second element has an R2 of -8.52. The third element, which is a meniscus, has an R3 of -24.69. The lens has an effective focal length (EFL) of 15mm, and the edge thickness is 8.88mm, while the center thickness is 9.86mm. The lens also has a small aperture of 3mm at the center.
The lens is made from N-BASF64 and N-SF66 Schott glass, which are both high-quality materials known for their excellent optical properties. The lens is designed to correct chromatic aberration, making it ideal for applications that require high image quality and color correction.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
