49-327-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=45mm VIS-NIR 400-1000nm

The 49-327-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the visible to near-infrared spectrum, spanning 400-1000nm. The lens is specifically designed for use in a variety of applications, including but not limited to, imaging, beam shaping, and focusing.

The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring high-quality optical performance. The use of these materials in a doublet configuration helps to correct chromatic aberration, a common issue in optical systems, providing clear, focused images.

The lens has an effective focal length (EFL) of 45mm, making it suitable for use in systems where a moderate focal length is required. The lens has a center thickness of 3.5mm, with a edge thickness of 3.94mm, providing robustness and durability. The lens also features an inner radius of 0mm and an outer radius of 0mm, indicating a symmetrical design.

The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing reflection and increasing transmission.
