Integrating sphere needs to be used together with spectroradiometer to the spectral, photometric and colorimetric parameters of all kinds of lighting sources.The traditional integrating sphere is assembled by several pieces. Lisun Group developed A Molding Technology to produce the sphere. A Molding Integrating Sphere will be more round and the test results will be more accuracy than the traditional integrating sphere. Integrating sphere can be designed according to customer’s request.
