32-859 18.0mm Dia. x 72.0mm FL; Uncoated; Plano-Convex Lens
The 32-859 is a Plano-Convex lens with a diameter of 18.0mm and a focal length of 72.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for their 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 18.0mm, the thickness edge is 1.9mm, and the thickness center is 3.0mm. The effective focal length (EFL) is 72.0mm, and the radius of curvature (R1) is 37.22mm. The back focal length (BFL) is 70.05mm, and both the inner and outer radii are 0mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is designed to operate at a wavelength of 587.6nm. The shape of the lens is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
