VIS Spectroradiometer

spectraval 1501

 

specbos 1501 is a precise and economic reference grade spectroradiometer for various applications including monitor and projector calibration and the measurement of different display types. It comes with the versatile radiometric software JETI LiVal, but can be used with different external programmes as CalMAN (spectracal), ChromaPure (Display Calibrations), LightSpace (LightIllusion), Argyll and HCFR (under preparation).
