LumiTop X20 / X30: Highest measuring accuracy meets maximum flexibility

The LumiTop X series was specially designed to meet the increasingly demanding measurement tasks in display measurement technology while providing a high degree of flexibility to the customer. The new LumiTop X20 and LumiTop X30 form the latest generation featuring the innovative 3-in-1 concept of our LumiTop test systems.

Extended measuring range

Due to the high sensitivity of the LumiTop X20 / X30 and internally switchable ND filter, these units offer a dynamic range of mcd/m² to Mcd/m². They deliver precise results, particularly for measurements at very low luminance.

Flexibility in the laboratory and production

The electronic focus enables the user to change quickly and easily between samples of different sizes. The excellent repeatability of the focus drive is specially designed for use in the production area.

The innovative LumiTop design combines the short measurement times of the CMOS RGB camera with the absolute accuracy of the spectral reference measurement. Together with the integrated fast photodiode for measuring flicker and modulation frequency, all relevant optical tests can be performed in a single test station.
