63-708 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=30mm VIS 0° 425-675nm
The 63-708 is a high-quality achromatic doublet lens, sourced from Edmund Optics, featuring a 10 mm diameter and an effective focal length (EFL) of 30 mm. This lens is specifically designed for use within the visible light spectrum, spanning 425-675 nm.
The lens is constructed from two distinct materials, N-BK7 and N-SF5, both from Schott. The N-BK7, a borosilicate crown glass, is known for its excellent optical properties, including low dispersion and high homogeneity. The N-SF5, a fluorite crown glass, offers a low refractive index and low dispersion, making it ideal for achromatic applications.
The lens features a standard coating on both the front and back surfaces. This coating, referred to as 'edm vis-0 std curve', is designed to enhance the lens's performance within the visible light spectrum.
The lens's geometry is carefully designed to optimize its performance. It has an inner radius of 0 mm and an outer radius of 0 mm. The edge thickness measures 4.48 mm, while the center thickness is 3.5 mm. The lens also features a first radius (r1) of 18.58 mm and a second radius (r2) of -13.17 mm. The third radius (r3) is -37.11 mm.
