49-315-INK 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=27mm VIS-NIR 400-1000nm

The 49-315-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400 to 1000 nanometers.

The lens features a 9 millimeter diameter and an effective focal length (EFL) of 27 millimeters, making it suitable for a wide range of optical applications. The doublet is composed of two elements, the first made from N-BK7 Schott glass and the second from N-SF5 Schott glass. This combination helps to minimize chromatic aberration, ensuring sharp and clear images.

The lens geometry is meticulously designed, with a central thickness of 3.89 millimeters and edge thickness of 4.26 millimeters. The first and second radii of curvature are 15.36 millimeters and -12.01 millimeters respectively, while the third radius of curvature is -39.56 millimeters. This specific geometry contributes to the lens's excellent optical performance.

The lens is coated with Edmund Optics' VIS-NIR-0SP2002000 coating on both the front and back surfaces. This anti-reflection coating is designed to maximize transmission in the 400-1000 nanometer range, further enhancing the lens's performance in its intended spectral range.
