The 32-856 is a Plano-Convex lens with a diameter of 12.0mm and a focal length of 84.0mm. 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 base shape, which is circular, and its thickness. The edge thickness is 2.08mm, while the center thickness is 2.5mm. The effective focal length (EFL) is 84mm, and the radius of curvature (R1) is 43.43mm. The back focal length (BFL) is 82.39mm, and both the inner and outer radii are 0mm.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to work with a wavelength of 587.6nm. The lens's shape is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
