Product Description


High purity porous alumina ceramic of 99% Al2O3 content, used extensively for long-life laser reflectors. This material is sintered at high temperatures to achieve a controlled porosity


Prime Features

1) Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity
2) 97% reflectance efficiency at 600-1000nm
3)Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve)
4)Controlled porosity
5)Good thermal conductivity
6)High electrical resistivity
