Independent of the application, whether in satellite optics, video lenses or endoscopes - aspheres have already become indispensable in a wide range of highly versatile technical fields of application. Regardless of the system’s size, they all have to meet one requirement: to be precise. To meet quality requirements, continued development of aspheric production and the trend towards miniaturization demand for faster and more accurate measuring methods. Different measuring methods are used depending on measuring task and speed as well as surface structure. Among others, a distinction is made between non-contact and tactile measurement. The basic principle of measuring aspheric components during production based on tactile measuring methods is presented in the following.
