49-772-INK 12.7 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=19.1mm VIS 0° 425-675nm
The 49-772-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.7 mm, is designed for use in the visible light spectrum, specifically between 425 and 675 nm. The lens boasts an effective focal length (EFL) of 19.1 mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6, which are carefully selected to minimize chromatic aberration, a common issue in optical systems. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, which enhances its light transmission capabilities and overall performance.
The lens geometry is meticulously designed, with a center thickness of 5.25 mm and an edge thickness of 4.72 mm. The inner and outer radii are 0, indicating a circular shape. The lens also features a central thickness 'a' of 1.5 mm.
This lens is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information, including technical specifications and purchasing options, users are encouraged to visit the provided weblink.
