This is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface, available from Standa. The lens has a circular base shape and is designed for use in the visible light spectrum, specifically at a wavelength of 546 nanometers.
The lens has a diameter of 38.1 millimeters and a thickness at the edge of 3.5 millimeters. The center thickness is slightly greater at 4 millimeters. The effective focal length (EFL) of the lens is 700 millimeters, which is the distance from the lens's center to the point where parallel rays of light converge after passing through the lens.
The lens is made from N-BK7 Schott glass, a high-quality borosilicate glass commonly used in optical applications due to its excellent optical properties and chemical resistance. The lens does not come with any coating, which means it is uncoated. This may affect the lens's performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
