The fundamental goal in the coin business to produce and maintain highest quality levels for coins in circulation. In order to achieve this goal optical vision systems are used to inspect the coins and coin blanks during the production process and can be used to inspect fit and unfit coins in circulation. Spaleck Oberflächentechnik GmbH & Co. KG is offering optical validation technology with this regard, called Spaleck Inspection Technology (SIT).

SIT is consisting of the mechanical transportation system of
items and the camera and analysing module. Both can be adjusted and adapted on specific customer needs. The system meets the market need for integrated
production systems, where quality control is a self-evident part of production,
and it is able to deliver a 100% control including full digital documentation.

SIT is not only capable to use normal light but also laser analysis in order to perform 2D and even 3D camera inspection technology. 3D technology is able to measure exact geometrical features of a workpiece in milliseconds from all dimensions of a workpiece. Despite the coin obverse and reverse, SIT offers additionally the optical edge inspection of coin and coin
blanks as well.
