Monrovia-based Ondax, which develops laser products and holographic gratings used in defense, industrial, medical diagnostics, analytical instrumentation, and consumer electronics markets, has added Andrea Belz to its board, the firm said Monday. The firm, which recently completed a $2.0M, Series E funding round from the Pasadena Angels and Tech Coast Angels, said Belz will represent both of those angel groups on its board. Belz was the lead investor on the funding round. Ondax is a spinoff of the California institute of Technology, and is headed by Randy Heyler. Belz is President of Belz Consulting Group.
