The transparent poly-crystalline spinel substrate* recently received an Award for Technical Advancement from the Japan Fine Ceramics Association.
This award is granted to prominent inventors of ingenious new products or technologies in the field of fine ceramics. Sumitomo Electric successfully commercialized and mass-produced transparent poly-crystalline spinel substrates, transparent in the mid-infrared to visible range, using a low-cost powder metallurgy process and precisely controlling substrate composition, structure and amounts of impurities. We are exploring the application of this product in various fields, one example being the projector heat spreader.
Sumitomo Electric will continue to provide products useful in various fields.
