PAC18AR.15 25 mm Dia. N-FK5/N-F2 Achromatic Doublet; EFL=100mm UV-VIS 345-700nm
The PAC18AR.15 is a high-quality achromatic doublet lens from the renowned optical vendor MKS/Newport. This lens, with a catalog number PAC18AR.15, is specifically designed for UV-VIS applications, covering the spectral range of 345-700nm.
The lens features a circular geometry with a diameter of 25mm and a thickness of 5.6mm at the edge. The inner and outer radii are zero, indicating a flat surface. The effective focal length (EFL) of this lens is 100mm, making it suitable for various optical applications.
The lens is composed of two types of glass, N-FK5 and N-F2, both from Schott. This combination helps to correct chromatic aberration, a common issue in optical systems. The lens is coated with New AR-15 on both the front and back surfaces, reducing reflective losses and improving transmission.
The lens geometry includes a center thickness of 5mm for the first element, 2.5mm for the second element, and a total center thickness of 7.5mm. The first and second radii of curvature are -50.72mm and -141.71mm, respectively.
This lens is available for purchase directly from the MKS/Newport website, and the link provided is valid and indicates the lens is in stock.
