This is a Plano-Convex lens, a type of spherical lens, sourced from Holmarc Opto-Mechatronics. The lens has a base shape of a circle and a diameter of 50mm. The thickness of the lens at the edge is 3mm. The effective focal length (EFL) of this lens is 500mm, making it a high-powered lens suitable for various applications.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner radius of the lens is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 260.808mm.
The lens is coated with BBAR (Broadband Anti-Reflection) coating, which is designed to reduce reflection and increase transmission over a broad spectrum of wavelengths, specifically 400-700nm. This coating is applied to both the front and back surfaces of the lens.
