45-276 20.0mm Dia. x 150.0mm FL; Uncoated; Plano-Convex Lens
The 45-276 is a Plano-Convex lens with a diameter of 20.0mm and a focal length of 150.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens's geometry is characterized by its diameter, thickness edge, and thickness center. The diameter is 20.0mm, the thickness edge is 2.35mm, and the thickness center is 3.0mm. The effective focal length (EFL) is 150.0mm, which is the distance from the lens's principal point to the focal point. The radius of curvature (R1) is 77.52mm, and the back focal length (BFL) is 148.02mm. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is designed to work with a wavelength of 587.6nm. The lens's shape is spherical, which is the most common shape for optical lenses due to its ease of manufacturing and good optical performance.
