63-720-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 63-720-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 400-1000nm. The lens features a 10mm diameter and an effective focal length (EFL) of 30mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass. These materials are chosen for their excellent optical properties, contributing to the lens's high-performance capabilities. The lens is also inked, which aids in its identification and handling.
The geometry of the lens is carefully crafted, with a thickness at the edge of 4.48mm and a center thickness of 3.5mm. The lens also features a curvature radius of 18.58mm on the first surface, -13.17mm on the second surface, and -37.11mm on the third surface. This complex geometry is designed to minimize chromatic aberration, a common issue in optical systems.
The lens is coated with Edmund Optics' VIS-NIR-0SP2002000 coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing reflection and increasing transmission.
