PAC061AR.14 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=175mm 430-700nm
The PAC061AR.14 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the visible light spectrum, spanning from 430nm to 700nm. The lens boasts a diameter of 25.4mm and an effective focal length (EFL) of 175mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass. These materials were chosen for their excellent optical properties, particularly their low dispersion, which helps to minimize chromatic aberration. The lens features a complex geometry, with a center thickness of 6.3mm, an edge thickness of 5.2mm, and radii of curvature of -78.493mm and -234.186mm for the first and second elements, respectively.
The PAC061AR.14 is coated with a New AR-14 coating on both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens. The lens is available for purchase directly from the MKS/Newport website, where it is listed as in stock.
