63-710 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm VIS 0° 425-675nm

The 63-710 is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length of 50 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 directly from their website.

The lens is constructed from two distinct materials: N-BK7 and N-SF5, both from Schott. N-BK7, a borosilicate crown glass, is known for its excellent optical properties, including low dispersion and high homogeneity. N-SF5, a fluorite crown glass, offers a low refractive index and low dispersion, making it an ideal choice for achromatic lenses.

The lens features a sophisticated geometry, with a thickness of 3.89 mm at the edge, a center thickness of 3 mm, and a center thickness 'a' of 1.5 mm. The lens's inner and outer radii are 0, and it has a first radius (r1) of 26.22 mm and a second radius (r2) of -23.95 mm. The lens's third radius (r3) is -97.55 mm.

The 63-710 lens comes with standard anti-reflective coatings on both the front and back surfaces. These coatings, Edmund Optics' VIS-0 STD curve, are designed to minimize surface reflections and improve light transmission, thereby enhancing the overall performance of the lens.
