PAC082 38.1 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=300mm MgF2 400-700nm
The PAC082 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 type, featuring a base shape that is circular, with a diameter of 38.1mm.
The lens is constructed from two types of materials, N-BK7 and N-SF5, both from Schott. These materials are known for their excellent optical properties, making them ideal for use in a wide range of optical applications. The lens features an effective focal length (EFL) of 300mm, which is a common choice for many optical systems due to its versatility.
The geometry of the lens is carefully designed to optimize its performance. The edge thickness of the lens is 9.6mm, while the center thickness is 11mm. The lens also features inner and outer radii of 0mm, and the curvature radii are r1=-134.16mm and r2=-401.214mm.
The lens is coated with MgF2, a broadband antireflection coating that is highly effective in the visible spectrum. This coating is applied to both the front and back surfaces of the lens, further enhancing its performance.
