49-301-INK 5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=15mm VIS-NIR 400-1000nm

The 49-301-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 5 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 a variety of applications that require precise optical performance.

The lens features an effective focal length (EFL) of 15mm, making it suitable for use in compact optical systems. The achromatic design of the lens helps to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. This is achieved through the use of two different types of glass, N-BAF10 and N-SF10, in the doublet lens.

The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating developed by Edmund Optics. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving transmission.

The lens has a center thickness of 1.55mm and an edge thickness of 2.22mm. The inner and outer radii of the lens are 0mm, indicating a flat surface. The lens's geometry is designed to provide excellent optical performance while maintaining a compact form factor.
