Innovacera Ceramic laser reflectors are high reflectance cavities used in solid state and CO2 laser systems. It is made of high purity 99% porous alumina ceramic and sintered at high temperatures to achieve a controlled porosity. 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. Prime Features - Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity - 97.8% reflectance efficiency at 600-1000nm - Reflectance efficiency exceeds 96% across the wavelength range 500-1200nm (see curve) - Controlled porosity, Good thermal conductivity, High electrical resistivity. Part No.: BAB330(TCT117) Dimension: Φ31.00xΦ12.00x117 mm Ph...

Source: https://www.innovacera.com/news/innovacera-ceramic-laser-reflectors.html INNOVACERA® ceramic laser reflectors are high-efficiency diffuse reflectors. The perfect diffuse reflection and high reflection efficiency are effectively exploited in laser systems in the 500 nm to 1200 nm spectral range. INNOVACERA® ceramic reflector is approximately 15-18% porous and virtually no absorption losses. It is suitable for dry cavity laser applications such as low energy air-cooled systems and higher energy laser systems The curve shown below illustrates the reflectivity of the INNOVACERA® ceramic reflector. Ceramic laser reflectors reduce and eliminate many of the shortcomings of PTFE polymer reflectors, polished metal specular reflectors, and packed powder diffuse reflectors. Here are some advantages of ceramic reflectors. - Ceramic material is strong to resist breakage if a flashlamp explodes - Glazed surfaces are corrosion resistant, allowing direct contact with coolants - There is no pl...
