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.

Automated Visual Inspection
In defect inspections, the use of automatic inspection equipment makes it possible to detect defects as small as 5 μm, leading to improved and more stable delivery quality.
