Alumina reflector

ceramic for solid-state lasersround

Innovacera manufactures custom and standard ceramic reflector designs for flash lamps, continuous-wave lasers, diode-pumped lasers, and cosmetic surgery markets. Ceramic Reflector is made by 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 material properties: Bulk density (fired), Mg/m3:3.1 Color: White 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 Ceramic Reflector features: Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity Resists chemical attack Controlled porosity Has high strength Good thermal conductivity High electrical resistivity We can machine or grind ceramic reflectors against the customer’s drawing. Quantities range from prototype to production quantities. Glazing protects the surface in preventing adhesion of impurities and primarily ensures leak tightness of the reflectors.
