Optical integrating sphere operates at visible and infrared wavelengths
An optical integrating sphere with a faceted reflective lining on the inside surface will provide light randomization /mixing of diffusely and specularly reflected light/ with relatively few reflections. The improved sphere has a sufficiently high reflectivity for both visible and infrared radiation.
