Readability of an E-reader is affected by surface gloss. The Vates can measure diffuse reflectance and gloss from different angles and it's high speed allows to perform a surface scan of the display or analyse response time behaviour of the E-reader.
The Vates is a compact solution which can be used for in-line and off-line analysis and supports both contacting and non-contacting measurement.
