PAC097 76.2 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=750mm MgF2 400-700nm
The PAC097 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically for wavelengths between 400 and 700nm. This lens is a multiplet, meaning it is composed of multiple optical elements, in this case, two, made from N-BK7 and N-SF5 Schott glass.
The lens has a diameter of 76.2mm and a total thickness of 15.2mm, with the edge being 15.2mm thick and the center having a thickness of 17.5mm. The effective focal length (EFL) of the lens is 750mm, and it has a curvature radius (r) of 455.878mm, with the first (r1) and second (r2) radii being -336.756mm and -1010.204mm, respectively.
The PAC097 features a MgF2 coating on both the front and back surfaces, which is designed to reduce reflection and increase transmission in the visible spectrum. This coating is applied using a new process developed by Newport, specifically for this lens, ensuring optimal performance.
The lens is currently in stock and available for purchase directly from the MKS/Newport website, with a valid link provided in the item data for easy access.
