II-VI, Inc. develops, manufactures and markets optical and optoelectronic components used in the laser, military and nuclear radiation detection industries. Its laser-related products include laser gain materials for solid-state lasers and many of the high-precision optical elements used to focus and direct laser beams to target or work surfaces. Its military infrared products include targeting and navigation systems that utilize advanced optical materials. Its nuclear radiation detector products are based on the semiconductor material cadmium zinc telluride (CdZnTe). These detectors are designed for increased performance, reduced size, improved ruggedness and lower-voltage requirements. The II-VI has also expanded to the manufacture of single crystal silicon carbide (SiC) for use in solid-state lighting, wireless infrastructure, radio frequency (RF) electronics and power switching industries.
