Temperature in the UV Aging Test Chamber: the temperature in the chamber shall be controlled according to the specified test procedure when the equipment is in the irradiation stage or in the lighting stop stage, and the relevant specifications shall specify the temperature to be reached at the irradiation stage of 40 ℃ or 55 ℃ according to the intended use of the equipment or components; Air ...
I. The Structure and Basic Principle of Optical Integrated Sphere The basic principle of an optical integrated sphere is to have a light source at the center of the sphere which emits light which is then diffused onto the coating on the inner walls of the sphere. The diffused light passes through diffusion and continues to cycle until the light flux is the same across the entire inner surface of t...
