Introduction:

Alumina-based ceramic reflectors are reportedly ideal for a wide variety of industrial and healthcare applications, including cutting and welding, marking, or even hair and tattoo removal. Our ceramic cavities are made of a porous high-purity alumina (96% Al2O3) providing high strength, good thermal conductivity, and excellent dimensional and electrical stability in the operating temperature range.

Application:
Intense pulsed light systems
Solid-state lasers
Ceramics for Excimer Lasers
Ceramics for CO2 Lasers
Ceramics for Ion Lasers

Advantages:
The alumina material is chosen for its excellent microstructure and its control of defined porosity, which provides excellent reflectance of the laser light.The material provides a highly diffuse reflectance, behaving as a bulk reflector of the source of radiation by both reflecting and refracting light back into the cavity.
It has a good thermal conductivity and excellent dimensional and electrical stability at all operating temperatures.

Features:
Controlled porosity
Good thermal conductivity
High electrical resistivity
Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity
