49-953-INK 15 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=20mm VIS-NIR 400-1000nm
The 49-953-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 15 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 features a focal length (EFL) of 20mm, making it suitable for a wide range of optical applications. The achromatic design, achieved through the combination of N-BAF10 and N-SF57 Schott glass types, ensures minimal chromatic aberration, a common issue in optical systems.
The lens geometry includes a thickness of 5.98mm at the edge, with a central thickness of 6.8mm. The curvature radii are R1 = 14.01mm, R2 = -11.36mm, and R3 = -44.21mm. The lens is coated with EDMM VIS-NIR 0SP2002000 on both the front and back surfaces, enhancing its performance in the specified wavelength range.
This lens is available in a multiplet configuration, offering versatility and customization options for various optical system designs.
