In many applications today, camera systems must be integrated into very compact spaces. Well-known examples are smartphones and cars. One component of such cameras is a short focal length objective lens. To ensure a perfect image on a very close camera chip, it is important to determine the flange focal length precisely. This online event presents the new OptiSpheric® HR as an efficient solution for this crucial measuring task. The OptiSpheric® is the industry standard for non-contact testing of basic axial optical and opto-mechanical parameters such as effective and back focal length (EFL and BFL), flange focal length (FFL), radius of curvature (RoC) and modulation transfer function (MTF). It is used worldwide to measure and qualify single lenses and optical lens assemblies comprehensively. This industry standard has been further enhanced to meet the needs of samples with particularly short focal lengths. Thus, the OptiSpheric® HR can now test lenses with an EFL from 0.3 mm to 12 mm. It is especially designed for the very precise determination of the flange focal length (FFL) with a measuring accuracy of ±4μm and the repeatability of 2μm. This product demonstration will illustrate the basic characteristics of OptiSpheric®. Against this background, the enhancements of the OptiSpheric® HR and their advantages for the measurement of FFL of short focal length lenses will be highlighted and measurements on the system will be demonstrated.
