Heateron Ceramic Laser Reflector/ Ceramic Diffuse Reflector Customized Available.
Description
Ceramic Reflector is a 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.
Features
- Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity
- 97.8% reflectance efficiency at 1000nm
- Reflectance efficiency exceeds 96% across the wavelength range 500-2000nm (see curve)
- Controlled porosity
- Good thermal conductivity
- High electrical resistivity
Applications
Pumping chambers for Nd:YAG lasers � low to high power, single or multiple lamp designs. Pumping chamber reflectors of this material are virtually indestructible, and prove a highly cost effective alternative to metal coated types.
