This is a Plano-Convex lens, a type of spherical lens, sourced from CeNing Optics. The lens has a circular base shape with a diameter of 12.7 mm and a thickness at the edge of 1.8 mm, while the center thickness measures 2.8 mm. The effective focal length (EFL) of this lens is 40 mm.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The inner and outer radii of the lens are 0, indicating a plano-convex geometry where one side of the lens is flat (plano) and the other side is curved (convex).
The lens is designed to operate at a wavelength of 546.1 nm. It does not have any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
The lens is currently in stock and available for purchase. More information about this product can be found on the vendor's website.
