PAC079AR.14 38.1 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=250mm 430-700nm

This is the PAC079AR.14, a high-quality achromatic doublet lens from the renowned optical components manufacturer, MKS/Newport. The lens is specifically designed for use in the visible light spectrum, spanning from 430nm to 700nm.

The lens features a multilayer anti-reflective coating (AR-14) on both the front and back surfaces, which significantly reduces surface reflections, thereby enhancing transmission and image quality. The coating is applied using a precise figure-from process, ensuring superior optical performance.

The PAC079AR.14 has a diameter of 38.1mm and a thickness of 9.8mm at the edge. The lens's geometry includes an effective focal length (EFL) of 250mm, an inner radius of 0mm, and an outer radius of 0mm. The lens's center thickness is 11.5mm, with individual center thicknesses of 7.5mm and 4mm for the first and second surfaces, respectively.

The lens is composed of two types of glass: N-BK7 from Schott and N-SF5 from Schott. These materials were chosen for their excellent optical properties, particularly their low dispersion, which helps to minimize chromatic aberration.

The PAC079AR.14 is currently in stock and available for immediate purchase from the MKS/Newport website. For more information, please refer to the provided catalog number and weblink.
