Since 1941, HOYA has been a premier provider of optical glasses. Over the years, this traditional material business has transformed into a key element in the development of advanced electronics and information technologies. HOYA has invested heavily in technical innovation to satisfy advanced requirements as well as to increase our commitment to environment preservation. Such commitments include the removal of lead, arsenic and other non‐environmentally friendly chemicals. Our goal is to leverage our technology to fulfil our customers’ needs, while contributing to the environment and society.
HOYA keeps supporting the optical industry that has progressed significantly in recent times through our high-quality optical glass, which is widely used for optical elements in telescopes, binoculars, lens shutter cameras, interchangeable lens, office automation apparatuses, video cameras, digital cameras, and mobile phone cameras.
Raw material is available in coarse or fine annealed options. Our extrusion melting method (E‐bar form) yields glass in strip form – not block. The two opposite surfaces, although not polished, permit visual internal inspection. The remaining four sides are fire‐polished or as cast.
