PAC14AR.16 25 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=35mm NIR-IR 750-1550nm
The PAC14AR.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 constructed from two materials, N-LAK22 and N-SF6, both from Schott, which are renowned for their optical quality and durability.
The lens features a plano-convex geometry, with a diameter of 25mm and a thickness of 10.48mm at the edge. The inner radius is 0mm, while the outer radius is also 0mm, indicating a symmetrical design. The effective focal length (EFL) of the lens is 35mm, making it suitable for a wide range of optical applications.
The lens is coated with New AR-16e on both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens.
The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of chromatic aberrations, ensuring high-quality imaging across the entire spectral range. The lens has a front radius of curvature (R) of 23.4mm, a first back radius (R1) of -20.11mm, and a second back radius (R2) of -87.52mm. The thickness at the center of the first element is 11mm, while the thickness at the center of the second element is 4mm, resulting in a total center thickness of 15mm.
