Since the foundation in 1949, Yamamura Photonics put a technical development in the core competence technique of the glass material and the glass-to-metal seal (GTMS) technology grown by vacuum tubes, and we have been developing business.

Corresponding to the electronics device change from vacuum tubes to semiconductors, we supply various products for photonics and electronics synergy field. Currently three major fields of businesses are formed.

(1)Electric and electronics glass components
(2)Opto-electronics packaging components
(3)Glass ceramics (LTCC)

New technical development is quickly advancing in the latest IT and the digital product field with the core technology of opt-electronics. Responding to such market needs, Yamamura Photonics continuously challenges to the development and manufacturing of unique components and material with the key word of "Photonics and Electronics"
