PAC079 38.1 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=250mm MgF2 400-700nm
The PAC079 is a high-quality achromatic doublet lens from MKS/Newport, designed for visible light applications within the 400-700nm spectrum. This lens, with a diameter of 38.1mm, is a multiplet type, featuring a complex geometry that ensures superior optical performance.
The lens's geometry includes an effective focal length (EFL) of 250mm, a center thickness of 11.5mm, and edge thickness of 9.8mm. The inner and outer radii are 0mm, and the curvature radii are r1=-112.149mm, r2=-336.34mm, and r=151.578mm. These specifications contribute to the lens's high optical performance and precision.
The PAC079 is made from two types of high-quality Schott glass: N-BK7 and N-SF5. These materials ensure excellent transmission and low dispersion, making the lens suitable for a wide range of applications. The lens is coated with MgF2, which further enhances its performance by reducing reflection and increasing transmission.
This lens is available from MKS/Newport and is currently in stock, according to the vendor's website. For more information, including pricing and availability, please refer to the provided web link.
