PAC06AR.16 12 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=40mm NIR-IR 750-1550nm
The PAC06AR.16 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the near-infrared and infrared spectrum, with a wavelength range of 750-1550nm. The lens is part of the Multiplets category, featuring a circular base shape with a diameter of 12mm.
The lens geometry is intricately designed, with a center thickness of 7mm, an edge thickness of 6.12mm, and an effective focal length (EFL) of 40mm. The lens's inner and outer radii are 0mm, and it has a front curvature radius of 22.81mm and a back curvature radius of -21.91mm. The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, ensuring high optical quality and durability.
The PAC06AR.16 is coated with New AR-16E on both the front and back surfaces, enhancing its performance in the infrared spectrum. This coating reduces surface reflections, improves transmission, and increases the lens's overall efficiency. The lens's shape is a multiplet, which is a combination of two or more individual lenses to achieve specific optical properties.
