PAC058 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=150mm MgF2 400-700nm
The PAC058 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically between 400-700nm. This lens is a multiplet type, featuring a base shape that is circular, with a diameter of 25.4mm.
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 applications. The lens features an effective focal length (EFL) of 150mm, 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 is 4.9mm, while the center thickness is 6.167mm. The lens also features a range of radii, including r=91.273mm, r1=-67.225mm, and r2=-200.644mm. These parameters are crucial in determining the lens's optical properties.
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.
The PAC058 is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.newport.com/p/PAC058.
