49-392-INK 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=200mm VIS-NIR 400-1000nm
The 49-392-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 50 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000 nm. The lens boasts an effective focal length (EFL) of 200 mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of high-grade Schott glass: N-BAK4 and N-SF10. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens is coated with EDMM VISNIR0SP2002000, a proprietary coating developed by Edmund Optics, which enhances its transmission capabilities in the VIS-NIR spectrum.
The lens geometry is intricately designed, with a center thickness of 9 mm and edge thickness of 9.11 mm. The lens features three radii of curvature: r1 at 130.48 mm, r2 at -99.36 mm, and r3 at -320.2 mm. These parameters contribute to the lens's excellent imaging capabilities.
The 49-392-INK is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
