49-304-INK 6.25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=12.5mm VIS-NIR 400-1000nm

The 49-304-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 6.25 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens is specifically designed for use in multiplet configurations, making it an ideal choice for complex optical systems.

The lens features an effective focal length (EFL) of 12.5mm, providing a compact and efficient optical solution. The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott, ensuring high optical quality and performance. The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating from Edmund Optics, on both the front and back surfaces, enhancing its transmission capabilities in the VIS-NIR spectrum.

The lens geometry includes a thickness of 3.12mm at the edge, with a central thickness of 3mm and a central thickness 'a' of 0.8mm. The lens's curvature is defined by radii r1, r2, and r3, which are 8.63mm, -5.29mm, and -51.17mm respectively. The lens's inner and outer radii are 0, indicating a circular shape.

The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
