This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 48-754, has a diameter of 18.0mm and a focal length of 36.0mm, making it a compact yet powerful optical element.
The lens is made from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a plano-convex geometry, meaning one side is flat while the other side is curved.
The lens's geometry includes a thickness of 1.25mm at the edge and 3.57mm at the center. The effective focal length (EFL) is 36.0mm, and the radius of curvature (R1) is 18.62mm. The back focal length (BFL) is 33.65mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' standard NIR-I coating on both the front and back surfaces. This coating is specifically designed for the 600-1050nm wavelength range, enhancing the lens's performance in the near-infrared spectrum.
