63-723-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS-NIR 400-1000nm
The 63-723-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens is 10mm in diameter, making it suitable for a wide range of applications.
The lens is constructed from two types of materials, N-BK7 and N-SF5, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens features an effective focal length (EFL) of 100mm, providing a long focal length that can be beneficial in many applications.
The lens's geometry is carefully designed to optimize its performance. It has a thickness of 3.7mm at the edge, ensuring structural integrity while minimizing unnecessary weight. The lens's inner and outer radii are 0, indicating a circular shape that can provide a wide field of view. The r1, r2, and r3 radii are 60.99mm, -43.74mm, and -130.98mm, respectively, contributing to the lens's complex but precisely engineered curvature.
The lens's center thickness is 2.5mm, and the center thickness 'a' is 1.5mm. These dimensions are crucial for accurate optical modeling and design. The lens is coated with edm visnir0sp2002000 on both the front and back, enhancing its performance in the VIS-NIR spectrum.
