The Hohenstein White Scale is used to consistently adjust UV content in spectrophotometer or tristimulus devices to the daylight. Requirements:
- A measuring device with an illumination similar to daylight (preferably a xenon lamp)
- Sufficient UV light
- Corresponding equipment at the device to adjust the UV light
Hohenstein's Illumination Control Samples are used to check UV content stability in the colorimeter over longer periods of time. This enables reproducibility of illumination conditions.
The Hohenstein White Scale is consistently calibrated according to the corresponding device types.
