To celebrate 20 years Precisiebeurs and the fact that we were back, we treated our visitors to a nice piece of celebration cake!

We enjoyed many inspiring conversations and took the opportunity to present our newest [ARINNA in-line interferometer ](https://www.ibspe.com/measuring-systems/optical-measuring-systems)developments and solutions. 

Below video shows our optical measuring system ARINNA in action, performing measurements with nanometre accuracy on three different samples. This included printed solar cells for the automotive industry. On the surface of these cells 100nm laser patterned features were measured live at the show.

 

The theme of this year's show: 20 year precision engineering. We were ask to send in a representation of this long term development in precision technology. For this special exposition we created a display showing 20 years of development in our machine qualification systems.

Details of this  development over the last 20 years:

2002 - First machine qualification system with cabled electronics  
2006 - Head size reduction, 10x higher accuracy  
2012 - On-board electronics, wireless communications by WIFI  
2013 - 10x higher accuracy, 12x battery lifetime  
2022 - 2x head size reduction, 90x battery lifetime, 10x thermal stability
