Yellow Ceramic Reflectors
The yellow-glazed ceramic laser reflector cuts off wavelengths in the UV range which reduces the amount of heat generated in the laser head. It exhibits high reflectivity in the main absorption band of the solid-state laser, and at the same time exhibits the function of reducing the reflectivity in the ineffective absorption band. As a contrast, the diffuse reflective ceramic condenser cavity has high reflectivity in the non-absorptive ultraviolet band of the laser crystal, but it cannot effectively filter out the ultraviolet light that produces a harmful color center to the laser crystal. The highly reflective, UV-absorbing yellow glazed ceramic glaze can obviously improve the shortcomings of ordinary ceramic laser reflector. It has the characteristics of strong laser radiation resistance, high insulation, corrosion resistance, easy cleaning, and UV absorption. It extends the service life, reduces cooling requirements and in some cases reduces operating costs.
The ceramic reflector green body is made of 99% Al2O3, and the green body is fired at an appropriate temperature to retain proper porosity and proper green strength. The surface of the reflector is fully coated with high-reflectivity ceramic glaze. Compared with the gold-plated reflector, the biggest advantage lies in its extremely long service life and diffuse reflection. Main features:
1. Dimensional tolerance in height direction can achieve tolerance ≤1.0mm, other dimensional tolerances can reach ≤0.5mm
2. The surface is fully glazed to achieve maximum reflectivity and easy to clean
3. The reflectivity reaches 97% at the wavelength of 600-1000nm
4. The reflectivity exceeds 95% in the wavelength range of 380-1100nm
5. The body has proper porous and high strength characteristics Main physical characteristics:
Flexural strength: 170Mpa
Thermal expansion coefficient: 7.9×10-6--/С（200～500℃）
