N-9000NS
Nishimura Advanced Ceramics manufactures Translucent Alumina ceramic which has high total light transmittance and high mechanical strength like single crystal sapphire.
Since N-9000NS is produce from pure fine grain Alumina, it has higher intensity than other translucent alumina.
It has even better mechanical strength than sapphire, therefore it can be substitute of sapphire.
N-9000NS is based on 99.99% Alumina.
