Versions

The are several version of this device:

• The 2012 model (aka v1.0) that have shown degradation of plastic holders due to ozone pollution
• The 2014 model (aka v2.0) with plastic housing material. BBO Crystal are glued using a ceramic bridge. Ozone pump added to the LgswUnit to suck out the ozone produced by the cells
• The July 2015 model (aka v2.1) of PockelsCells is un upgraded version with different housing material (replacing piezoelectric PVDF) and different electrical pins layout and internal wiring improved. Same mechanical interface of v2.0
