Spectraval is a compact spectroradiometer for the visible spectral range. It is available in a version without display (1501) and one with display (1511). Both can be used for spectral Radiance measurement with a measuring angle of 2°. The actual measuring area is marked by a red circle.
Spectraval 1511 can be operated in stand alone mode or in connection with a computer.
Spectraval 1501 always needs a computer, but can be used with several special programs, e.g. for monitor calibration.
Advantages:- Compact solutions
- Fast measurement
- Precise results due to high quality spectrograph and NIST traceable calibration

- Color adjustment of digital projectors
- Measurement of LED displays
- Luminance, Radiance
- xy and u'v' coordinates, RGB values
- Dominate wavelength, color purity
- Correlated Color Temperature
- Color Rendering Index
- Radiometric spectrum
