NIRFlex N-500

 Operation Manual, Version G

4 .2 .3 

Transmission mode

NIR light is sent through a defined pathlength of sample material (e.g. in a cuvette). The transmitted 
light contains the spectral information. This is the preferred method for testing liquids.

Detector

Cuvette

NIR light

pathlength

4 .2 .4 

Diffuse transmission mode

The diffuse transmission mode is a mixture of “diffuse reflection” and “transmission” mode. 

The NIR light penetrates the sample:
•  is refracted
•  diffusely reflected
•  diffusely transmitted

The transmitted rays contain the spectral information of the sample.

Detector

NIR light

Sample

Collecting lens
