63-691 4 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=10mm MgF2 400-700nm
The 63-691 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens features a 4mm diameter and an effective focal length (EFL) of 10mm, providing a compact yet powerful optical solution. The lens is constructed from two types of high-quality Schott glass, N-BAF10 and N-SF10, which are known for their excellent optical properties.
The lens is coated with EDM MgF2 standard curve coatings on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving overall image quality.
The geometry of the lens is carefully designed to optimize its optical performance. The lens has a thickness of 2.65mm at the edge, reducing to 2mm at the center, and 1mm at the center a. The radii of the lens surfaces are also precisely controlled, with r1 at 7.12mm, r2 at -4.22mm, and r3 at -33.66mm.
