This is a 14BCX150-2-1 Double-Convex Lens, sourced from the reputable vendor Standa. The lens boasts a diameter of 50.8 mm and a focal length of 150 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 or protect it from environmental factors.
The lens is spherical in shape, with a base shape of a circle. The geometry of the lens is defined by its diameter, thickness edge, thickness center, and effective focal length (EFL). The diameter is 50.8 mm, the thickness at the edge is 2 mm, and the thickness at the center is 6.1 mm. The EFL, which is the distance from the lens to the point where it focuses light, is 150 mm.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The lens is designed to work with a wavelength of 546 nm. The radii of curvature for the first and second surfaces of the lens are 154.56 mm and -154.56 mm, respectively. The lens does not have any inner or outer radius.
