The PAC19AR.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 types of Schott glass, N-LAK22 and N-SF6, which provide excellent optical performance and durability.
The lens features a plano-convex geometry, with a 25mm diameter and a thickness of 7.98mm at the edge. The effective focal length (EFL) of the lens is 75mm, making it suitable for a wide range of optical applications. The lens's front and back surfaces are coated with New AR-16e, a broadband anti-reflective coating that reduces surface reflections and improves transmission.
The lens's design includes two curved surfaces, with radii of curvature of 43.96mm and -42.9mm for the first surface, and -392.21mm for the second surface. The lens has a central thickness of 10mm, with the first and second centers having thicknesses of 6mm and 4mm, respectively. The lens's shape is a multiplet, indicating that it is composed of multiple elements.
