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 6 mm and a thickness of 1.5 mm at the edge, gradually increasing to 2.27 mm at the center. The effective focal length (EFL) of this lens is 12 mm.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The radius of curvature for this lens is 6.22 mm, and the back focal length (BFL) is 10.5 mm. The lens does not have any coating, as indicated by the 'Uncoated' status in the item data.
The lens is designed to operate at a wavelength of 546.1 nm. The 'Material ID' field suggests that the lens is made of n-bk7 schott, a specific type of N-BK7 glass. The lens's geometry is spherical, and it is available from the vendor's website, as indicated by the 'weblinks' field in the item data.
