47-874 15.0mm Dia. x 30.0mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 47-874 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 15.0mm and a focal length of 30.0mm, making it a compact yet powerful optical component. The lens is designed for use within the visible light spectrum, specifically between 425-675nm, and is coated with a VIS 0° coating on both the front and back surfaces.
The lens's geometry is characterized by a thickness of 1.25mm at the edge and 3.18mm at the center. The radius of curvature (R1) is 15.52mm, and the back focal length (BFL) is 27.9mm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The VIS 0° coating on the lens is a standard curve anti-reflection coating, designed to reduce surface reflections and increase transmission within the visible light spectrum. This coating is applied to both the front and back surfaces of the lens, further enhancing its performance.
