Glass rod products

Sumita Optical Glass serves the wide range of optical glass rods for applications that are used for small optical components such as ball lenses, rod lenses, and discs.
Processing small diameter which can not be performed in hand press, is possible.
As pressing products in the past, accuracy of outer diameter in small diameter and accuracy of thickness varied much. Thus, processing afterwards caused some problems. But, as cut bar products, we solved this problem. And, we made it possible to process in high accuracy.
