SPX055 50.8 mm Dia. x 300 mm FL; Uncoated; Plano-Convex Lens
The SPX055 is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of 300 mm, making it suitable for a wide range of optical applications.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This can be advantageous in certain applications where the natural properties of the material are desired. The lens is made from UVFS Mal-1965, a material known for its transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.
The geometry of the lens is carefully designed to provide optimal performance. The edge thickness is 3 mm, while the center thickness is 5.363 mm. The lens's inner radius is 0, and its outer radius, or base curvature, is 137.7 mm. The back focal length (BFL) is 296.32 mm, and the effective focal length (EFL) is 300 mm.
This lens is designed to work with a wavelength of 589 nm, making it suitable for applications that require precise focus at this wavelength. The lens's shape is spherical, which is a common choice for many optical systems due to its simplicity and predictable optical properties.
