PAC13AR.15 12.5 mm Dia. N-FK5/N-F2 Achromatic Doublet; EFL=50mm UV-VIS 345-700nm
The PAC13AR.15 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the UV-VIS spectrum, specifically between 345 and 700nm. This lens, with a catalog number PAC13AR.15, is a multiplet type, featuring a base shape that is circular. It is available for purchase directly from the vendor's website, where it is currently in stock.
The lens has a diameter of 12.5mm and a thickness at the edge of 4.55mm. The inner and outer radii are both zero, indicating a symmetrical design. The effective focal length (EFL) of this lens is 50mm. The curvature radii are r1=-29.11mm and r2=-71.39mm, and the thickness at the center is 5.5mm, with individual center thicknesses of 3.5mm and 2mm for the first and second elements, respectively.
The lens is made from two types of materials: N-FK5 and N-F2, both from Schott. These materials are known for their excellent optical properties, making them suitable for a wide range of applications. The lens is coated with New AR-15 on both the front and back surfaces, which helps to reduce reflections and increase transmission.
