Abstract
An ophthalmological measuring system, for obtaining biometric data of an eye, provided with the necessary calibration and check devices for monitoring the functionality and the calibration status. The ophthalmological measuring system includes an illumination source for illuminating an eye with light and with a sensor for recording and analyzing back-scattered or reflected light components and a controller. At least one calibration and check system integrated in the ophthalmological measuring system for monitoring the functional and calibration status is provided. A device is also provided which houses the calibration and test structures and which reads off the individual physical data therefrom by an interface. The ophthalmological measuring system is in particular provided for determining biometrical data but can also be used for ophthalmological, dermatological or other devices which require calibration and/or functional checking at regular intervals.
