PAC016 6.35 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=25.4mm MgF2 400-700nm

The PAC016 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible light spectrum, specifically between 400 and 700nm. This lens is a multiplet, meaning it is composed of multiple optical elements, in this case, two, to achieve superior optical performance.

The lens has a diameter of 6.35mm and an effective focal length (EFL) of 25.4mm, making it suitable for a wide range of applications where compactness and high performance are required. The lens's geometry includes an inner radius of 0 and an outer radius of 0, with a thickness at the edge of 2.5mm. The first and second radii of curvature are -11.266mm and -33.538mm, respectively, while the thickness at the center is 2mm for the first element and 1mm for the second, resulting in a total center thickness of 3mm.

The lens is made from two types of glass: N-BK7 from Schott and N-SF5 from Schott. These materials were chosen for their excellent optical properties and ability to minimize chromatic aberration, a common issue in optical systems. The lens is coated with MgF2, a broadband anti-reflection coating that enhances transmission in the visible spectrum.
