|
spectraval 1501 is a precise and economic reference grade spectroradiometer for various applications including monitor and projector calibration and the measurement of different display types (download datasheet). 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). A diffusor for the Irradiance measurement can be ordered separately (ACC 032). |
