PAC18AR.16 25 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=60mm NIR-IR 750-1550nm
The PAC18AR.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 constructed from two materials, N-LAK22 and N-SF6, both from Schott, which are renowned for their optical quality and durability.
The lens features a plano-convex geometry, with a diameter of 25mm and a thickness of 9.46mm at the edge. The inner radius is 0mm, while the outer radius is also 0mm. The effective focal length (EFL) of the lens is 60mm, making it suitable for a wide range of optical applications.
The lens is coated with New AR-16E, a high-performance anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's transmission characteristics, reduces surface reflections, and increases overall system efficiency.
The lens is a multiplet, meaning it is composed of multiple elements. This design provides superior imaging performance, reduced chromatic aberration, and increased optical clarity. The lens has a center thickness of 12mm, with individual center thicknesses of 8mm and 4mm for the two elements.
