You must specify the waveband you want to work, the configuration (reflectance, transmitance, etc.), work space, light, camera and sample locations, etc.

Hello Rasool,

Light chamber means especially it should come in Visible to Near Infra Red Band,SO you required so better used with Multispectral Imaging and this you can work with CIE chromaticity diagram. ok bye

do you want to do this in either a small enclosure or a room? either way, the wall color is important. there is an ISO standard grey for this, as colored or bright walls will definitely change your results from reflected light. also, do not wear loud Hawaiian shirts while working!

Dear  Dr. Greg Bearman,

Thanks very much for your information.
