The 45-207-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 5 mm diameter, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is a multiplet, featuring a geometry that includes an effective focal length (EFL) of 15mm. The lens's design includes three radii (r1, r2, and r3) and two thicknesses (thickness edge and thickness center), which contribute to its excellent optical performance. The inner and outer radii are 0, indicating a circular shape. The lens's thickness at the edge is 2.22mm, while the thickness at the center is 1.55mm. The thickness at the center 'a' position is 1.03mm.
The lens is composed of two materials, N-BAF10 and N-SF10, both from Schott. These materials are known for their high refractive indices and low dispersion, making them ideal for achromatic doublet lenses. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, which provides excellent broadband anti-reflection performance.
The lens's catalog number is 45-207-INK, and it is currently in stock. For more information, including pricing and availability, please refer to the provided weblink.
