CAPX15 25.4 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The CAPX15 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 200 mm, sourced from the reputable vendor MKS/Newport. This lens is uncoated, which means it does not have any additional layers to alter or enhance its optical properties.
The lens's geometry is characterized by a thickness of 1.5 mm at the edge and 2.999 mm at the center. The radius of curvature (R1) is 62.735 mm, and the inner radius is 0 mm. The effective focal length (EFL) is 200 mm, which is the distance from the lens's principal point to the focal point when the lens is imaging an object at infinity.
The lens is made of CAF2 (Calcium Fluoride) material with a Mal-1963 grade. This material is often used in optical systems due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The specific wavelength for this lens is 2940 nm.
