47-701-INK 15 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm VIS 0° 425-675nm
The 47-701-INK is a high-quality achromatic doublet lens, sourced from Edmund Optics, with a diameter of 15 mm and a focal length of 40 mm. This lens is designed for use within the visible light spectrum, specifically between 425-675 nm. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.
The lens features a standard curve coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The lens's geometry is also noteworthy, with a central thickness of 5.98 mm and edge thickness of 6.38 mm. The lens's inner and outer radii are zero, indicating a symmetrical design.
The lens's design includes three radii (r1, r2, and r3), which contribute to its overall optical performance. The first radius (r1) is 26.97 mm, the second radius (r2) is -17.64 mm, and the third radius (r3) is -205.03 mm. These radii, in combination with the lens's material and coating, contribute to the lens's ability to bring light to a focus while minimizing chromatic aberration.
