The 47-662-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 light spectrum, specifically between 425 and 675 nanometers. The lens boasts an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are known for their excellent optical properties. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its performance in the visible light spectrum.
The lens geometry is intricately designed, with a center thickness of 5mm, an edge thickness of 4.9mm, and a central thickness 'a' of 1.25mm. The lens curvature is also precisely engineered, with radii r1, r2, and r3 measuring 17.27mm, -10.99mm, and -107.03mm respectively. The lens is designed in a circular shape, with an inner radius and outer radius of 0mm, adding to its versatility.
