PAC049 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=88.9mm MgF2 400-700nm
The PAC049 is a high-quality achromatic doublet lens from the renowned optical vendor MKS/Newport. This lens, with a diameter of 25.4 mm, is designed for use in the visible spectrum, specifically between 400 and 700 nm.
The lens is a multiplet, meaning it is composed of multiple elements. The primary materials used in its construction are N-BK7 and N-SF5, both high-grade Schott glasses known for their excellent optical properties. The use of these materials ensures high light transmission and minimal chromatic aberration.
The lens has an effective focal length (EFL) of 88.9 mm, making it suitable for a wide range of optical applications. The geometry of the lens is carefully designed with a center thickness of 7.47 mm, edge thickness of 5.3 mm, and inner and outer radii of 0 mm. These parameters contribute to the lens's overall performance and durability.
The PAC049 is coated with MgF2, a broadband anti-reflection coating that further enhances its light transmission capabilities. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in both transmission and reflection.
