We control every production step in the manufacture of our Quartz Monitor Crystals, from the supply of the high Q raw Quartz to the precise Wire Saws used to cut the primary wafers.

Add to this a strictly controlled lapping and contouring process and you have the foundation for a superior Quartz Monitor Crystal.

By using our six stage proprietary washing process and angstrom level accuracy electrode plating, in a class 1000 clean room, we achieve a truly advanced Quartz Monitor Crystal of exceptional quality.
