49-322-INK 12.5 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=20mm VIS-NIR 400-1000nm
The 49-322-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 to 1000 nm. The lens features an effective focal length (EFL) of 20 mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 from Schott. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems. The lens is coated with EDm VIS-NIR 0SP2002000 on both the front and back surfaces, enhancing its transmission capabilities across the specified wavelength range.
The lens geometry is meticulously designed, with a central thickness of 5.25 mm and edge thickness of 4.62 mm. The radii of curvature for the three surfaces are R1: 13.98 mm, R2: -9.35 mm, and R3: -76.14 mm. The lens is shaped as a multiplet, a complex lens system made up of multiple elements, each with its own radius of curvature and thickness.
The lens is currently in stock and available for immediate purchase. For more detailed information, including pricing and availability, please refer to the provided weblink.
