PAC19AR.16 25 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=75mm NIR-IR 750-1550nm
The PAC19AR.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 types of Schott glass, N-LAK22 and N-SF6, which provide excellent optical performance and durability.
The lens features a plano-convex geometry, with a 25mm diameter and a thickness of 7.98mm at the edge. The effective focal length (EFL) of the lens is 75mm, making it suitable for a wide range of optical applications. The lens's front and back surfaces are coated with New AR-16e, a broadband anti-reflective coating that reduces surface reflections and improves transmission.
The lens's design includes two curved surfaces, with radii of curvature of 43.96mm and -42.9mm for the first surface, and -392.21mm for the second surface. The lens has a central thickness of 10mm, with the first and second centers having thicknesses of 6mm and 4mm, respectively. The lens's shape is a multiplet, indicating that it is composed of multiple elements.
This lens is available for purchase directly from MKS/Newport, and the provided item data indicates that it is currently in stock. The catalog number for this lens is PAC19AR.16, and more information, including pricing and availability, can be found on the MKS/Newport website.
