PAC077 38.1 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=200mm MgF2 400-700nm
The PAC077 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically for wavelengths between 400 and 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 38.1mm and an effective focal length (EFL) of 200mm, making it suitable for a wide range of optical applications. The lens is constructed from two types of high-quality glass, N-BK7 and N-SF5, both from Schott, ensuring excellent optical properties.
The PAC077 features a complex geometry, with a center thickness of 11mm, an inner radius of 0mm, and an outer radius of 0mm. The lens also has a thickness edge of 8.8mm, providing robustness and durability. The lens's shape is circular, contributing to its wide range of applications.
The lens is coated with MgF2 on both the front and back surfaces, enhancing its transmission capabilities in the visible spectrum. The coating is applied using a new mgf2bk7fromfigur process, ensuring high-quality and consistent performance.
