541-7207 25.4 mm Dia. x 75 mm FL; Uncoated; Plano-Convex Lens
The 541-7207 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 25.4 mm and a focal length of 75 mm. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens is uncoated, which means it does not have any additional layers to alter or enhance its optical properties.
The lens's geometry is defined by its diameter and thickness. The diameter is 25.4 mm, and the thickness at the edge is 2.5 mm. The lens's effective focal length (EFL) is 75 mm, which is the distance from the lens's principal point to the focal point. The radius of curvature (R1) of the curved surface is 38.4225 mm. The lens does not have an inner radius (R2), and the outer radius is also 0, indicating that the lens is not threaded or has any other additional features on its outer surface.
The lens is made of Barium Fluoride (BaF2), identified by the Material ID "baf2 cgdm". This material is commonly used in the ultraviolet and infrared spectrum due to its high transparency in these regions. The wavelength of this lens is 3000 nm, which falls within the infrared spectrum.
