ER Precision Optical has recently invested over 2 million dollars in our new expansion in crystal growing. We are now fully functional with four crystal pullers and have more than doubled our capacity.

Our new expansion specializes in optical and solar grade Germainium and Silicon. ERPOC is now one of few companies to grow and manufacture crystals in the USA. Materials are 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 around 36-72 hours depending on the material.

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.
