This is the LP01-50-100 50.8 mm Dia. N-BK7 Plano-Convex Lens, a high-quality optical component sourced from CeNing Optics. The lens, which has a diameter of 50.8 mm, is designed for use in a variety of optical systems, thanks to its precise geometry and high-quality materials.
The lens is a Plano-Convex type, meaning it has one flat surface and one curved surface. The curvature of the lens is defined by a radius of 51.88 mm, which is measured from the center of the lens to the edge of the curved surface. This curvature, combined with the lens's overall length of 9.65 mm (measured at the center), gives the lens an effective focal length (EFL) of 100 mm.
The lens is made from N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. This specific lens is uncoated, meaning it does not have any additional layers applied to its surfaces to alter its optical properties. However, it is important to note that the lens is designed for use at a wavelength of 546.1 nm.
The lens's geometry is defined by its diameter and thickness. The diameter is 50.8 mm, while the thickness at the edge is 3 mm. The lens's inner and outer radii are both 0 mm, indicating that the lens is a simple Plano-Convex design.
