PAC04AR.16 12 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=30mm NIR-IR 750-1550nm

The PAC04AR.16 is a high-quality optical lens from MKS/Newport, designed for use in the near-infrared and infrared spectrum, specifically between 750nm and 1550nm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.

The lens features a plano-convex geometry, with a diameter of 12mm and a thickness of 5.82mm at the edge. The inner and outer radii are zero, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) of the lens is 30mm, making it suitable for a variety of optical applications.

The lens is made from two types of Schott glass, N-LAK22 and N-SF6, which are known for their excellent optical properties in the NIR and IR ranges. The lens is coated with New AR-16e on both the front and back surfaces, which reduces reflection and increases transmission in the NIR and IR ranges.

The lens has three curvature radii (r, r1, and r2) and three thicknesses (thickness edge, thickness center 1, and thickness center 2). The center thickness is 7mm, while the edge thickness is 5.82mm, and the thicknesses at the centers of the two curvatures are 4.5mm and 2.5mm, respectively.
