32-498-INK 30 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=75mm MgF2 400-700nm
The 32-498-INK is a high-quality Achromatic Doublet lens, boasting a 30 mm diameter and a focal length of 75mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website. The product page indicates that the item is currently in stock, ensuring prompt delivery.
The lens is constructed from two types of glass, N-SSK8 and N-SF10, both from the reputable Schott glass catalog. This combination of materials helps to correct chromatic aberration, a common issue in optical systems, thereby enhancing the overall image quality.
The lens features a front and back coating of MgF2, a material known for its excellent optical properties. This coating is part of Edmund Optics' standard curve, which is designed to provide optimal performance across the visible light spectrum, specifically within the 400-700nm range.
The lens geometry is also noteworthy. It has a thickness of 8.4mm at the edge and center, with an inner radius and outer radius of 0mm. The curvature of the lens is defined by radii of 40.51mm and -38.68mm for the first and second surfaces, respectively, and -922.04mm for the third surface. This complex geometry contributes to the lens's high-performance capabilities.
