The PAC01AR.16 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the near-infrared and infrared spectrum, specifically between 750nm and 1550nm. This lens is part of the Multiplets subtype, featuring a base shape of a circle.
The lens has a diameter of 12mm and a thickness at the edge of 8.41mm. The inner radius is 0mm, and the outer radius is also 0mm. The effective focal length (EFL) of this lens is 18mm, making it suitable for a variety of optical applications. The lens's front and back surfaces are coated with New AR-16e, a broadband anti-reflection coating designed for high performance in the NIR-IR spectrum.
The lens's geometry is intricate, with a first radius (r1) of -8.65mm and a second radius (r2) of -37.28mm. The thickness at the center of the first surface is 8mm, while the thickness at the center of the second surface is 2.5mm, resulting in a total center thickness of 10.5mm.
This lens is made from two types of Schott glass: N-LAK22 and N-SF6. These materials were chosen for their excellent optical properties in the NIR-IR spectrum. The lens is a doublet, meaning it is composed of two separate elements, which are cemented together to form a single, high-performance lens.
