All Viso systems are delivered pre-calibrated. When recalibration is needed, it is possible to do this yourself. Viso recommends calibration every year (minimum every two years) using your own calibration light source as CALI-DT300 or CALI-T50.
REF-800 is a light sources that makes it possible for you to check your calibration status regularly
Labarazzi is a special TLA generator that can be used to calibrate flicker measurement devices or cameras – or for flicker demonstration purposes.
Dedicated Viso light sources are fully integrated with the Viso Light Inspector software
