This is a product line of processed products using sapphire grown by our company.

Sapphire wristwatch window with Mohs hardness "9", second only to diamonds. Shinkosha is the one and only manufacturer in Japan.

For group-III nitride semiconductor, typified by blue and white LEDs. Small warpage and excellent parallelism are achieved.

Single crystal type evaporation material. Our material contains no binding material and reduces outgassing and splash.

Optimal oxide crystal substrates for epitaxial growth. These are made by integrated & in-house production ranging from crystal growth to substrate finishing.

We provide high quality crystals with our unique crystal growth method.

Our isolators can surely suppress unstable operations in laser output, such as power fluctuations, frequency fluctuations, modulation bandwidth limitation, and LD destruction.

Optical fiber sensor created by the fusion of crystal and optical technology. It helps disaster prevention and mitigation.
