PAC095AR.14 76.2 mm Dia. N-BK7/N-F2 Visible Achromatic Doublet; EFL=250mm 430-700nm

The PAC095AR.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 76.2 mm diameter, making it suitable for a wide range of optical applications.

The lens is constructed from two types of glass: N-BK7 and N-F2, both from Schott. This combination ensures superior optical performance, minimizing chromatic aberration and delivering clear, sharp images. The lens features an effective focal length (EFL) of 250mm, providing the necessary magnification for detailed observations.

The PAC095AR.14 lens is coated with New AR-14 fromfigure on both the front and back surfaces. This anti-reflective coating enhances the lens's performance by reducing unwanted reflections and increasing transmission, thereby improving image brightness and contrast.

The lens geometry is carefully designed to optimize its optical performance. It has a thickness of 11.7mm at the edge, with the inner and outer radii being 0mm. The first and second radii of curvature (r1 and r2) are -101.72mm and -456.06mm, respectively, while the thickness at the center is 14.5mm for the first surface and 4mm for the second surface, totaling 18.5mm.
