PAC088AR.14 50.8 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=250mm 430-700nm
The PAC088AR.14 is a high-performance 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 50.8mm diameter, making it suitable for a wide range of optical applications.
The lens is constructed from two types of high-quality glass: N-BK7 from Schott and N-SF5 from Schott. These materials are carefully selected for their excellent optical properties, ensuring superior image quality and color correction. The lens features a focal length of 250mm, indicated by the EFL (Effective Focal Length) value.
The PAC088AR.14 lens is coated with New AR-14 fromfigure on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections, thereby increasing transmission and improving overall system performance.
The lens geometry is meticulously designed, with a center thickness of 12.83mm, an edge thickness of 9.7mm, and radii of 151.578mm, -112.149mm, and -335.971mm for the first and second surfaces, respectively. These parameters are optimized to provide the best possible optical performance.
