JETI has announced the addition of 2 new Spectroradiometers to the JETI probes family.
These meters has been demonstrated already at Laser World of Photonics exhibition @ Munich (22-25 Jun 2015) and they they will be available @ IBC 2015, The World's Premier Broadcast Technology Event @ Amsterdam (11-15 September 2015). I will update this thread about any further news / availability / pricing once they will be available.
JETI's 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.
Advantages:
Compact solutions
Fast measurement
Precise results due to high quality
spectrograph and NIST traceable calibration
Comfortable handling due to Bluetooth connection
Examples for applications:
Calibration of broadcast monitors
Color adjustment of digital projectors
Measurement of LED displays
Spectraval 1511 can be operated in stand alone mode or in connection with a computer.
Spectraval 1511 displays the following values:
Luminance, Radiance
xy and u´v´ coordinates, RGB values
Dominate wavelength, color purity
Correlated Color Temperature
Color Rendering Index
Radiometric spectrum
Spectraval 1501 always needs a computer, but can be used with several special programs, e.g. for monitor calibration.
