Ceramic Reflector

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.

All Surface Glazed Alumina Ceramic Reflector

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.
