49-935 5 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=12.5mm VIS 0° 425-675nm
The 49-935 is a high-quality Achromatic Doublet Lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 5 mm diameter and an effective focal length (EFL) of 12.5mm, designed for use within the visible light spectrum, specifically between 425-675nm.
The lens is constructed from two types of Schott glass, N-SSK8 and N-SF56, which are carefully selected to minimize chromatic aberration, a common issue in lens systems. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its light transmission capabilities and overall performance.
The lens geometry is meticulously designed, with a thickness of 2.78mm at the edge, 2.3mm at the center, and 1mm at the center-A position. The lens curvature is defined by radii R1, R2, and R3, which are 8.57mm, -6.22mm, and -21.36mm respectively. The lens's inner and outer radii are both zero, indicating a circular shape.
The lens's availability and in-stock status are confirmed, with a valid weblink provided for users to directly access the product page on the Edmund Optics website. This lens is a reliable choice for various optical applications, offering excellent image quality and performance.
