Ceramic Reflector
Innovacera Ceramic laser reflectors are high reflectance cavities used in solid state and CO2 laser systems. It is made by high purity 99% porous alumina ceramic and sintered at
high temperatures to achieve a controlled porosity.
Our range of custom ceramic reflectors offer significant advantages and improvements
over those made with materials such as metal and polymer, it work particularly well in Ruby and Nd: YAG laser pumping chambers and used extensively for long-life laser reflectors.
Ceramic reflectors can be glazed both inside the cavity and around the outer edges using a highly reflective glaze that seals the ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and efficiencies. Glazes can also act as filters and our glazed reflectors have been used successfully in certain applications.
