PAC052 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=100mm MgF2 400-700nm

The PAC052 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 100mm, 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 r value is 60.741, and the r1 and r2 values are -44.71 and -133.104 respectively, indicating the curvature of the lens surfaces.

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

The PAC052 is currently in stock and available for purchase directly from the MKS/Newport website. With its superior optical performance, robust design, and wide range of applications, the PAC052 is an excellent choice for any optical system that requires a high-quality achromatic doublet lens.
