63-766 40 mm Dia. N-BK7/N-SF5 Negative Achromatic Doublet; EFL=-120mm MgF2 400-700nm
The 63-766 is a high-quality negative achromatic doublet lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens is designed with a base shape of 40 mm diameter and a focal length of -120mm, making it suitable for a wide range of optical applications.
The lens is composed of two types of glass, N-BK7 and N-SF5, both from Schott, a leading manufacturer of optical glass. This combination ensures excellent optical performance, minimizing chromatic aberration and delivering sharp, clear images. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, which enhances its light transmission capabilities within the 400-700nm spectrum.
The geometry of the lens is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a central thickness of 4mm. The edge thickness is 14.31mm, and the lens features three radii of curvature: r1=-72.65mm, r2=56.77mm, and r3=173.4mm. These specifications contribute to the lens's high performance and versatility.
