PRODUCT DESCRIPTION
Design completely according with international and domestic relevant standards, coating material of inner-wall selects pure barite ore (BaSO4) which has stability chemical property and will not turn yellow after long time later, material of sphere body choose cold rolled steel so that is not deformed. Base height is adjustable and ensures the integrating sphere is in level. Multiple interfaces can meet more lights’ requirement simultaneously.
Providing a good test condition to avoid light pollution and loss, integrating spheres with multiple detectors interface can meet both light and chroma test requirements

How to choose a suitable integrating sphere and baffle?

The size of integrating sphere is determined by the dimension of light-source, from 0.2m to 2m are optional. And the inner material of sphere can be diffuse reflection, like BASO4 powder; the baffle must be done at the lowest degree. At the luminous test mode, the shape of lamp and spectrum type should conformity with the standard light-source as possible as it can. In practice, the diameter of sphere should be as 6 times as diameter of standard light-source. But if the condition is limited, it would be better that the shape of lamp and spectrum type should conformity with the standard light-source as possible as it can.

The material quality of inner sphere will make a big effect for the measurement. Thus we choose the white coating to make the reflection coefficient be the lowest, as the BaSO4 and MgSO4 have the features of good chemistry stability, not easily turn yellow.

The baffle will also affects the test precise; the baffle will stop the detector receiving the direct lights from the light-source, it would be better to choose a small one. Generally, the baffle should be put between photo-detector and light-source.
