Ceramic Pump Chambers | High Reflectivity

Ceramic pump chambers works in the laser head as reflective substance. It is excellent diffuse reflection which works in laser welding machine, laser cutting machine, laser marking machine and many medical laser system.

We have the capability to custom design and manufacture the alumina ceramic laser cavity reflector. The product is in high precision, high reflectivity and long service life.

Working Temperature

Glazed: It is best not to keep the working temperature of glazed ceramic reflectors above 300℃ for a long time, otherwise crystallization may occur.
Non glazed: The working temperature of non glazed ceramic reflectors can be 1200℃.

Precautions for Use

1. Ceramic reflectors must not be severely damaged by external forces during transportation, storage, and assembly, such as falling off to the ground, forcefully pressing into the pipe shell due to inappropriate size, etc;
2. The semi glazed ceramic reflector must be sealed with the tube shell to prevent the ceramic reflector from inhaling a large amount of coolant, which may cause a decrease in power;
3. During assembly and maintenance, it is forbidden to scratch the ceramic reflective surface, which may cause a decrease in reflectivity, and the coolant may easily cause scaling on the ceramic surface during use;
4. When using short wavelength (such as 755nm) high-temperature systems, it is important to pay attention to the selection of cooling system piping and equipment materials to avoid contaminating the ceramic surface with free metal oxides.
