Cut Bar Products

Bar products are the rod-like optical glasses, preforms of cut bar products. Cut bar products can be produced by slicing them to the desired thickness and polishing. Cut bar products can be produced from low- to high-volume production, and even small lots are manufactured to high precision with consistent quality. Most of the glass types can be chosen to manufacture cut bar products.

Production quantities ranging from low volume to mass production can be accommodated. Mirror polishing at working surface is also available.
