Japanese company Ishihara Sangyo Kaisha has launched mass production of a new material, LUSHADE BLACK. It is an ultra-low reflectivity pigment capable of absorbing over 99% of visible light.
This development is ready for global market entry. These optical properties enable LUSHADE BLACK to suppress stray light. Furthermore, the material not only absorbs the visible spectrum but also reflects infrared radiation.
Coatings based on it generate less heat in sunlight. The pigment itself is based on bismuth sulfide and has a microstructure similar to that of sea urchin spines. This surface shape ensures near-complete absorption of light.
This technology paves the way for a wide range of applications for this material, from optics and photography to LiDAR systems and protective coatings. Other applications include coating lens edges to eliminate glare, treating the interior surfaces of cameras for clearer images, and creating infrared-reflective coatings.
