49-877 12.0mm Dia. x 20.0mm FL; Uncoated; Plano-Convex Lens
The 49-877 is a Plano-Convex lens with a diameter of 12.0mm and a focal length of 20.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. 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 geometry, which includes a diameter of 12.0mm, a thickness at the edge of 1.58mm, and a thickness at the center of 3.5mm. The effective focal length (EFL) is 20.0mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 17.69mm, 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.
