PAC061 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=175mm MgF2 400-700nm

The PAC061 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically between 400-700nm. This lens is a multiplet, meaning it is composed of multiple optical elements, in this case, two, to achieve superior optical performance.

The lens has a diameter of 25.4mm and an effective focal length (EFL) of 175mm, making it suitable for a wide range of optical applications. The lens's geometry is carefully designed with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission and minimal distortion. The lens's thickness at the edge is 5.2mm, while the center thickness is 3.8mm for the first optical element and 2.5mm for the second, totaling 6.3mm.

The PAC061 lens is made from two types of high-quality glass: N-BK7 from Schott and N-SF5 from Schott. These materials are chosen for their excellent optical properties, including high transparency and low dispersion. The lens is coated with MgF2 on both the front and back surfaces, which enhances its light transmission capabilities and further reduces dispersion.

This lens is currently in stock and available for immediate purchase from the MKS/Newport website. With its superior optical performance, robust design, and wide applicability, the PAC061 is an excellent choice for any optical system operating in the visible spectrum.
