Product Introduction This spectral universal integrating sphere is suitable for building different spectral measurement systems, with high cost-effectiveness and strong universality. When paired with corresponding accessories, it can be used as a uniform light source, laser power for spectral measurement, transmittance measurement, reflectance measurement, and more. The integral ball is designed with a universal opening, which can quickly install corresponding accessories according to different applications, meeting the multi-purpose needs of one ball. It is easy to operate and flexible to use. Customers can also customize the opening size and position according to specific needs. Jingyi Optoelectronics' integrating sphere adopts a diffuse reflective coating with high stability, excellent Lambertian characteristics, and high diffuse reflectance. The coating is not easy to yellow or peel off, which can achieve the best testing effect.
