Specbos 1211 is a broadband, quick spectroradiometer capable of detecting Vis to NIR range, providing fast and accurate luminance and chroma analysis. The following is its interior setup:

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:

l  Luminance, Radiance

l  Illuminance, Irradiance

l  xy and u'v' coordinates,RGB value

l  Dominant wavelength, color purity

l  Correlated Color Temperature

l  Color Rendering Index



l  Vis to NIR range

l  high sensitivity

l  both radiance and irradiance measuring modes

l  small and easy to use

l  NIST traceable calibration

l  Measurement also possible with DLLs or SCPI compatible commands

With Jeti Lival Software:
l  Intiuitive Operation
l  Weighing Spectrum with action function
l  Classification of Samples
l  Easy data export to Excel and CSV
