De Mavospec Base is een miniatuur high-end spectroradiometer voor dagelijkse metingen aan diverse conventionele en moderne lichtbronnen, zoals LEDs en OLEDs.

Alle gemeten grootheden zoals verlichtingssterkte (lux), kleurtemperatuur (correlated color temperature CCT), kleurweergave-index CRI of Ra (R1-R15), kleurweergave conform TM-30-15, kleurcoördinaten conform diverse CIE normen, Flicker (%, frequentie), spectrale vermogensverdeling, piekgolflengte en dominante golflengte, coördinaten in CIE diagram, photosynthetic photon flux density PPFD, TLCI-2012 “Television Lighting Consistency Index”, worden vastgesteld voor het gemeten spectrum en weergegeven op een dusdanige heldere wijze dat experts, maar ook leken de resultaten kunnen begrijpen.

Hierdoor kan de Mavospec Base Spectroradiometer gebruikt worden voor zeer uiteenlopende toepassingen zoals controle van een lichtontwerp, installatie en onderhoud van (verlichtings)systemen, R&D, productie en kwaliteitsborging van display panels, beoordelen van lichtbronnen en armaturen, het evalueren van tuinbouw (horticulture) toepassingen, televisie- c.q. opnamestudio’s, alsmede de evaluatie van ambient lichtparameters in psychologische en fysiologische onderzoeken.

Measured values can be saved in CSV format to the 4 GB microSD memory card integrated into the battery compartment either automatically for each measurement or manually by pressing a key. A new folder is created for each date and the filenames are based on the time of day. If the Mavospec Base Spectroradiometer is connected to the USB port at a PC, it appears as a disk drive and the measurement data can be transferred. CSV files can be read in to Excel directly (Macro’s needed), and can be further processed by the user in order to generate reports. A sample report is included in the scope of delivery and is located on the memory card.

Diverse communication capabilities via USB support data transmission and control with external software, as well as integration into stationary measuring systems. The open communication protocol and an Excel application sample are also included on the memory card or can be requested by sending an e-mail to Lichtconsult.
