PAC090 50.8 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=400mm MgF2 400-700nm
The PAC090 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum with a wavelength range of 400-700nm. This lens is a multiplet type, featuring a base shape that is circular with a diameter of 50.8mm. The lens is designed with an effective focal length (EFL) of 400mm, making it suitable for a variety of optical applications.
The lens is composed of two types of glass, N-BK7 and N-SF5, both from Schott. These materials are known for their excellent optical properties, contributing to the lens' high performance. The lens features a thickness of 11.1mm at the edge, with a center thickness of 13mm, distributed between two glass types. The first glass type has a thickness of 8mm at the center, while the second glass type has a thickness of 5mm at the center.
The PAC090 is coated with MgF2 on both the front and back surfaces, a coating known for its excellent transmission properties in the visible spectrum. This coating helps to reduce reflection and increase transmission, enhancing the overall performance of the lens.
The lens is currently in stock and available for purchase on the MKS/Newport website, with a direct link provided in the item data for convenience.
