49-394-INK 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=300mm VIS-NIR 400-1000nm
The 49-394-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 50 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens is a multiplet, featuring a complex geometry that includes three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge, center, and center-a. The effective focal length (EFL) of this lens is 300mm, making it suitable for applications that require a longer focal length.
The lens is constructed from two types of high-grade Schott glass, N-BAK4 and N-SF10, which are known for their excellent optical properties. The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating developed by Edmund Optics, which enhances its performance in the VIS-NIR spectrum.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website through the provided weblink.
