Equipment Design

I have considerable experience in the design and construction of the equipment used to grow crystals. I have designed and built many of my own crystal Czochralski pullers with characteristics unique to the requirements of the crystals being grown. I have also designed the complex mechanism for weighing the crystal while simultaneously rotating and pulling it. I have worked with both sealed (vacuum tight) and unsealed systems.

I offer a seed rotation and weighing system for use on both sealed and unsealed systems which has been proven out at several customers’ locations.  The video below shows the precision of the weighing mechanism while growing an actual Nd:YAG crystal.  The least significant digit on the load cell display is 10 mg.
