49-850 25.4mm Dia. x 63.5mm FL; Plano-Convex Lens Uncoated
The 49-850 25.4mm Dia. x 63.5mm FL is a plano-convex lens, uncoated and sourced from the renowned optical vendor, Edmund Optics. This lens, with a base shape of a circle, is a spherical lens, designed for a wide range of optical applications.
The lens has a diameter of 25.4mm, making it suitable for use in compact optical systems. The thickness at the edge of the lens is 2.19mm, while the thickness at the center is 4.75mm. This variation in thickness is crucial in determining the lens's optical performance.
The effective focal length (EFL) of this lens is 63.5mm. This is the distance from the lens's principal point to the focal point, and it significantly influences the lens's magnification and field of view. The radius of curvature (R1) of the lens is 32.82mm, and the back focal length (BFL) is 60.37mm. These parameters are essential in determining the lens's optical power and its suitability for specific applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is uncoated, meaning it does not have any anti-reflective coatings. This may result in higher reflective losses and lower transmission, but it also means the lens is more cost-effective and easier to clean.
The wavelength of this lens is 587.6nm, which is in the visible light spectrum. This makes the lens suitable for applications involving visible light, such as imaging and illumination systems.
