Due to the lighting fixtures self-absorption, if the integrating sphere is bigger, the test results will be more accuracy. LISUN can produce the super big ulbricht integrating spheres such as 2.5m, 3m, 3.5m and 4m. Other size can also be designed.

LISUN add the infrared anti-pinch device for safety. It will automatically stop closing the sphere if somebody is inside of the sphere.  Please refer to article The New Design 3m Electric Integrating Sphere for more information.
