Integrating sphere radiation source at large dynamic range: the integrating sphere, SΦ600mm across inside, is equipped with tungsten halogen light sources of different power that could be combined and regulated to puff out energy at different level. The instrument can be used for relative or absolute radiometric calibration for aerospace optical remote sensor, low light night vision camera and robot vision.
