In-house Manufacturing from Materials
We grow our own synthetic quartz crystals used as birefringent materials.
We grow a variety of synthetic quartz crystals suitable for optical components. One of these is a lineup of optical components using "N-Grade EX," a synthetic quartz crystal of the highest purity with greatly reduced impurities and excellent resistance for high power lasers.
