PAC037 12.7 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=88.9mm MgF2 400-700nm
The PAC037 is a high-quality achromatic doublet lens from MKS/Newport, designed for visible light applications with a wavelength range of 400-700nm. This lens is a multiplet type, featuring a base shape of a circle, and is constructed from two types of materials: N-BK7 and N-SF5, both from Schott.
The lens has a diameter of 12.7 mm and a thickness at the edge of 4 mm. The inner and outer radii are 0 mm each, and the effective focal length (EFL) is 88.9 mm. The lens's front and back surfaces are coated with New MgF2BK7 from Figur, ensuring optimal performance and durability.
The lens's geometry is carefully designed with a first radius (r1) of -39.663 mm, a second radius (r2) of -117.483 mm, and a center thickness of 3 mm for the first center and 1.5 mm for the second center, totaling 4.5 mm for the center thickness.
The PAC037 is currently in stock and available for purchase on the MKS/Newport website. For more information, users can refer to the catalog number, PAC037, or visit the provided weblink.
