Abstract: The invention relates to a measurement system for optically measuring an object, comprising a dental camera and an optical attachment. In this case the optical attachment comprises at least one lens, which is shaped and arranged in such a way that the optical attachment has a negative focal length so that a measurement field or a measurement volume of the dental camera is enlarged by the optical attachment.
