Alumina Ceramic Cavity Laser Reflectors Introductions : 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. Ceramic Reflector Prime Features: > Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity > 97% reflectance efficiency at 600-1000nm > Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve) > Controlled porosity > Good thermal conductivity > High electrical resistivity Ceramic Cavity Laser Reflectors Physical properties: > Color: White > Bulk density (fired), Mg/m3 :3.1 > Porosity (apparent), % nominal :22 > Flexural strength (ASTM C1161, 3-point), MPa :170 > Thermal expansion coefficient 200-500C, 10-6 /C 7.9 200-1000C, 10-6 /C 9.0
