Introduction

The UTP 9050 series is a universal tester platform for combined LED, display and vision tests. It unites a flexible camera system and a comprehensive software solution as well as easily configurable user interfaces and meets all demands towards the visual testing of LEDs and displays. Because of its modular and universal concept, it is a future-proof investment in testing equipment that can be expanded if this is required.

The UTP 9050 is suitable for measuring the colour and the accuracy of LEDs. The system can be calibrated with the help of reference samples. After calibration, it is able to test LEDs with high precision. One or more cameras provide the graphical material that is the basis for the test cycle.

In combination with the Display Test Toolkit the UTP9050 is also able to analyse and test displays regarding colour temperature und homogeneity.
