49-329-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=60mm VIS-NIR 400-1000nm
The 49-329-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 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 60mm, making it suitable for use in systems where a longer focal length is required. The lens's geometry includes an edge thickness of 4.21mm, an inner radius of 0mm, and an outer radius of 0mm. The center thickness is 3.5mm, with a center A thickness of 1.5mm.
The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces, enhancing its transmission capabilities in the visible to near-infrared spectrum. This coating helps to reduce reflection, increase transmission, and protect the lens surface from environmental damage.
The 49-329-INK is currently in stock and available for immediate purchase from the Edmund Optics website. With its high-quality construction, wide spectral range, and versatile design, this lens is an excellent choice for a variety of optical applications.
