PAC20AR.16 50 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=100mm NIR-IR 750-1550nm
The PAC20AR.16 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the near-infrared and infrared spectrum, with a wavelength range of 750-1550nm. The lens is part of the Multiplets category, featuring a circular base shape with a diameter of 50mm.
The lens geometry is intricately designed, with a thickness edge of 13.89mm and an EFL (Effective Focal Length) of 100mm. The inner and outer radii are 0mm, indicating a flat surface. The lens features two spherical surfaces, with radii of curvature (r) of 59.74mm for the first surface and -59.74mm for the second surface. The lens's thickness at the center is 20mm, with individual thicknesses at the first and second centers being 14.5mm and 5.5mm, respectively.
The lens is composed of two materials, N-LAK22 and N-SF6, both from Schott. These materials are known for their excellent optical properties in the infrared spectrum. The lens is coated with New AR-16E on both the front and back surfaces, enhancing its performance in the specified wavelength range.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
