PAC058AR.14 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=150mm 430-700nm
The PAC058AR.14 is a high-quality achromatic doublet lens, designed for use in the visible spectrum, specifically between 430 and 700nm. This lens, sourced from MKS/Newport, is a multiplet lens, featuring a complex geometry that is designed to minimize chromatic aberration, a common issue in lens systems.
The lens has a diameter of 25.4mm, making it suitable for a wide range of applications. The edge thickness of the lens is 4.9mm, providing a robust and durable structure. The lens features an effective focal length (EFL) of 150mm, which is a common focal length for many optical systems.
The lens is made from two types of glass: N-BK7 and N-SF5, both from Schott. These glasses have been carefully selected to provide the best possible performance in the visible spectrum. The lens features a front coating of New AR-14, and the back surface also has the same coating. This coating helps to reduce reflections and increase transmission, improving the overall performance of the lens.
The lens geometry is quite complex, featuring three radii (r, r1, and r2) and three thicknesses (thickness center 1, thickness center 2, and thickness center). This geometry is designed to provide the best possible performance, minimizing aberrations and distortions.
