The ideal choice for interferometric measurement applications
Long working distance and high numerical aperture
High quality flat field color correction design

The Sanfeng WLI Plan APO infinity correction objective is a high-resolution flat field apochromatic objective with a high numerical aperture designed specifically for white light interference applications. These objectives ensure a long confocal working distance of 60 millimeters while maintaining a more compact and lightweight design. Each objective lens includes an interference fringe adjustment device and a built-in beam splitter, which can accurately measure and control the interference fringe pattern. The magnification range of the Sanfeng WLI Plan APO infinity correction objective is 2.5 to 50 times, and it can be used in conjunction with a cylindrical lens with a focal length of 100 millimeters. These objectives are highly suitable for white light interferometry applications, such as vertical scanning interferometry (VSI), 3D surface contour measurement, dispersion and reflection measurement, and medical imaging
