49-964 20mm Dia. x 80mm FL Uncoated; UV Plano-Convex Lens
The 49-964 20mm Dia. x 80mm FL Uncoated; UV Plano-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 20mm, is designed for use in a variety of applications that require a spherical lens with a plano-convex geometry.
The lens features a base shape of a circle, with a thickness at the edge of 1.61mm and a center thickness of 3mm. The effective focal length (EFL) of this lens is 80mm, making it suitable for applications that require a longer focal length. The radius of curvature (R1) is 36.68mm, and the back focal length (BFL) is 77.95mm. The lens does not have an inner or outer radius, indicating a uniform thickness across the lens.
The lens is made from fused silica, specifically identified as fused sil mal-1965 in the item data. This material is known for its excellent optical properties, including high transparency across a wide spectrum, making it ideal for use in UV applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The wavelength for this lens is 587.6nm, which is in the visible light spectrum. This further emphasizes the lens's suitability for UV applications, where the ability to transmit UV light is crucial.
