When light passes through the measuring optics an optical fiber transmits the gathered information into the spectroradiometer. The spectrograph separates the gathered light and the detector analyzes it to yield the data. The data is then transmitted to the attached computer to display the spectrum, luminance, chroma, and other information.

Can be used to measure the following quantities:

1. Luminance, Radiance

2. Illuminance, Irradiance

3. xy and u'v' coordinates，RGB value

4. Dominant wavelength, color purity 

5. Correlated Color Temperature

6. Color Rendering Index

Highlights：

1. UV to NIR range

2. high sensitivity

3. both radiance and irradiance measuring modes

4. small and easy to use

5. NIST traceable calibration

6. Measurement also possible with DLLs or SCPI compatible commands
