The BBMS-2000 bidirectional reflection/transmission spatial distribution measurement system can measure the scattering characteristics of the material surface, including the material's transmission distribution BTDF/reflected light distribution BRDF, total reflection TIR/scattering TIS and color parameters. It is widely used in plastics, auto parts, and furniture. , textile, glass and many other fields, it can characterize the properties of the apparent color appearance of materials that change with angle, as well as appearance characterization such as material surface modification.

1) The system rotates through four axes (A-axis, B-axis, C-axis, D-axis), which can realize the measurement of the Detector around the entire spherical surface of the tested sample, and the illumination of the light source around the half-spherical surface of the tested sample, automatically and Quickly realize the illumination and reflectance/transmittance measurement of the entire space of the sample being tested.

2) The illumination and spot size are adjustable, and equipped with a monitoring Detector to detect and compensate for the impact of light source fluctuations on measurement.
1) A-axis rotation range: -90°- +90°
2) B-axis rotation range: 0°-360°
3) C-axis rotation range: -180°- +180°
4) D-axis rotation range: 0°- +90°
5) Extremely high angular accuracy: angular resolution: 0.01°
Repeat accuracy: 0.05°
Positioning accuracy: 0.1°
