49-314-INK 9 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=18mm VIS-NIR 400-1000nm
The 49-314-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 9 mm diameter, is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400 to 1000 nanometers.
The lens features an effective focal length (EFL) of 18mm, making it suitable for a wide range of optical applications. The achromatic design, achieved through the combination of N-BAF10 and N-SF10 Schott glass types, ensures minimal chromatic aberration, a common issue in lens systems.
The lens geometry is meticulously crafted, with a thickness of 4.49mm at the edge and 4.32mm at the center. The center thickness 'a' is 1.15mm. The lens curvature is defined by radii R1, R2, and R3, which are 12.37mm, -7.38mm, and -73.86mm respectively.
The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating by Edmund Optics, on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR spectrum, providing improved transmission and durability.
The lens is currently in stock and available for immediate purchase through the Edmund Optics website. For more detailed specifications and purchasing information, please refer to the provided weblink.
