PAC21AR.16 50 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=150mm NIR-IR 750-1550nm
The PAC21AR.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 subtype, featuring a circular base shape and a multielement design for superior optical performance.
The lens has a diameter of 50mm and an effective focal length (EFL) of 150mm. The geometry of the lens includes an edge thickness of 12.47mm, an inner radius of 0mm, and an outer radius of 0mm. The lens's center thickness is distributed between two elements, with a thickness of 11mm for the first element and 5.5mm for the second, resulting in a total center thickness of 16.5mm.
The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, which are renowned for their excellent optical properties in the NIR-IR spectrum. Both the front and back surfaces of the lens are coated with New AR-16e, a broadband antireflective coating that enhances transmission and reduces surface reflections.
This lens is a versatile and high-performing option for applications that require superior optical quality in the NIR-IR spectrum. It is currently in stock and available for immediate purchase through the MKS/Newport website.
