This is Gilbert Zhou, the vice general manager of Ultra Photonics Inc. I was a crystal engineer during 2002-2010 years. And because of some reasons, I and several directors who were in charge of growing, polishing and coating department left our previous company. Last year we established Ultra Photonics Inc to manufacture high quality BBO, LBO, wave plates and Glan polarizers.

We purchased the same type instruments, and use the same processing technique to fabricate LBO and BBO crystals. So I can promise our crystals' quality is as good as the highest quality in China.

If you are interested in our products, please just feel free to send e-mail to us.
