The material of
ceramic reflector is 99% Al2O3.Its green body is fired at a suitable temperature to retain the proper porosity and strength. The surface of the ceramic reflector is coated with a high reflectivity ceramic glaze ,so compared with the gold-plated reflector , its has long service life and diffuse reflection.
Prime Features
- Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity
- 98% reflectance efficiency at 600-1000nm
- Reflectance efficiency exceeds 96% across the wavelength range 400-1200nm (see curve)
- Controlled porosity, Good thermal conductivity, High electrical resistivity.
Physical Characteristics
- Color: White
- Density: 3.1Mg/m^3
- Porosity: 22%
- Flexural strength: 170Mpa
- Coefficient of thermal expansion:
7.9×10^-6--/С (200500)
9×10^-6/С (2001000)
Al2o3 Ceramic Reflector Applications:
1. Pumping chambers for flash lamp and continuous wave lasers using media such as Nd:YAG lasers, Alexendrite - low to high power,
single or multiple lamp designs used for welding, cutting, marking and in lasers.
2. Layered and segmented pumping chambers for diode pumped lasers
3. Intense Pulse Light (IPL) applications for cosmetic surgery
