Sales to the industrial market jumped 19% compared to the prior-year period, while military sales grew 15% and communications sales rose 6%. Sales into the automotive, consumer, and semiconductor capital equipment markets more than doubled, accounting for half of the company's growth in fiscal 2018.

The quarter's sound results came despite investments in new markets that will take time to pay off. "Our strategic investments in technology and manufacturing scale, including those aimed at keeping our product portfolio differentiated, continued during the early adoption phase of several new emerging markets," said II-VI CEO Vincent Mattera.
