Our Name and History II-VI "two-six"

The Roman numerals “II-VI” refers to column II and column VI of the Periodic Table of Elements. By chemically combining elements from these columns, II-VI produced the infrared optical crystalline compounds: Cadmium Telluride (CdTe), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS) and Zinc Sulfide MultiSpectral (ZnS MS). These compounds and others created from column II and column VI elements are commonly referred to as “II-VI Materials”. Founded in 1971 to create CdTe, company co-founder Dr. Carl J. Johnson paid homage to our II-VI Materials heritage by calling our new company “II-VI Incorporated”.
