Spectraval 1501 is een nauwkeurige en economische VIS-spectroradiometer van referentiekwaliteit voor diverse toepassingen, waaronder monitor- en projectorkalibratie en het meten van verschillende soorten beeldschermen. Hij meet de spectrale radiantie in het zichtbare bereik en levert een verscheidenheid aan integrale gegevens.

Speciale versies van het apparaat zijn spectraval 1501-HiRes (met een verhoogde optische resolutie), spectraval 1501-NIR (met een golflengtebereik tot 1000 nm) en spectraval 1501-LAN (met LAN-interface in plaats van Bluetooth).
