In our lives, powerful currents are generated due to lightning strikes or sudden closing of large power station switches, which can cause great damage to our electrical equipment. Therefore, we usually use surge immunity to simulate such situations and carry out tests to protect electrical equipment as much as possible. LISUN SG61000-5 surge generator provides a common basis for evaluating the re...

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...
