PAC05AR.16 12 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=35mm NIR-IR 750-1550nm
The PAC05AR.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 sub-type, featuring a circular base shape with a diameter of 12mm.
The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, which are renowned for their excellent optical properties in the infrared spectrum. The lens geometry includes an outer radius of 0mm, an inner radius of 0mm, and a thickness edge of 6mm. The effective focal length (EFL) of the lens is 35mm, with a center thickness of 7mm, providing a balance between image quality and compactness.
The lens features a plano-convex design, with a radius of curvature (r) of 20.23mm for the convex surface and -19.17mm for the first concave surface (r1). The second concave surface (r2) has a radius of -193.84mm. This design helps to minimize chromatic aberration, a common issue in lenses used in the infrared spectrum.
Both the front and back surfaces of the lens are coated with New AR-16e, a high-performance anti-reflective coating. This coating reduces surface reflections, improving light transmission and enhancing the overall performance of the lens.
The PAC05AR.16 is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please visit the MKS/Newport website using the provided weblink.
