Repainting work for the integrative sphere, 80 inches φ2m.

It is possible to create an integrating sphere coating that is strong, uniform, and has a high reflectance rate. It is also possible to create a white reflective surface using 100% barium sulfate without using a binder.

**Overview** An integrating sphere is a measurement tool used to assess the optical characteristics of light sources. It is composed of a diffuse reflective surface with high reflectivity on the inner surface of the sphere. The light emitted by the light source inside the sphere and the light entering the sphere are reflected multiple times, stabilizing the illuminance on the walls and allowing for the measurement of the optical characteristics of the light source by photometry of a portion of that light. Therefore, the reflective coating on the inner surface of the integrating sphere is particularly important. **Features** ◎ BaSO4 reflective surface with uniform and high reflectivity. ◎ Maintenance and regeneration are possible even if the diffuse surface becomes contaminated or deteriorated. ◎ Painting of integrating sphere accessories such as support bases and sockets is also possible. ◎ It has mechanical strength that can withstand mechanical vibrations. ◎ It excels in robustness, long-term stability, and weather resistance even in production environments. ◎ We also support repainting of deteriorated integrating spheres from other companies. **Painting Process** Pre-painting inspection (physical properties such as material, structure, flatness) ⇒ Reflectivity measurement under condition d(8/di) (repainted integrating sphere) ⇒ Pre-treatment (rust prevention treatment, flatness treatment, etc.) ⇒ Painting work (at our factory/customer site) ⇒ Reflectivity measurement under condition d(8/di) ⇒ Submission of "Reflectivity Inspection Report."
