ER Precision Optical has recently invested over 2 million dollars in our new expansion in crystal growing. We will be fully functional with four crystal pullers by the end of 2009 and will more than double our capacity by spring of 2010.

Our new expansion will specialize in optical and solar grade Germainium and Silicon. ERPOC will now be one of few companies to grow and manufacture crystals in the USA. Materials will be available in full ingot form , generated blanks, or as finished product.

Our Kayex 6000 models are capable of growing 10" diameter ingots with modified growing techniques. Lead time for full ingots is less than 36 hours.

ERPOC can also regrade your old materials, saving you money. ER Precision Optical remains committed to the highest level of quality at the most competitive prices.
