The system uses tried-and-tested mechatronic components to provide fast, accurate and reliable measurements of automotive, rail and other vehicle headlamps. Additionally, it can be used for photo-metric characterization of traffic signal lamps and airfield lighting systems. This goniophotometer system is designed for lamps of up to 50 kg and the x,y translation stage surface size is 400 x 400 mm.
Controllable and programmable
Depending on the application the system can be paired with the following measuring instruments:
GL PHOTOMETER 3.0 LS + Flicker
GL SPECTIS 1.0 LS
GL SPECTIS 5.0
A selection of peripheral devices for tests of vehicle headlamps is available.
GLG A 50-1800 Usage
Larger capacity
Production and development teams constantly improving lamps and fixtures make more efforts to provide specifications of their products and verify compliance. This creates increasing demand for faster and more flexible light measuring systems. As changes in the industry are speeding up and products are getting more sophisticated, the need for testing and verification becomes more critical.
This type A GL Goniophotometer can be used in factory laboratories as well as in accredited laboratories and deliver fast and reliable results for the measurements of small and lager lamps. Mechanical design includes increased load capacity up to 50kg, large 400x400mm mechanical stage and 3 motorized axis featuring absolute encoders for improved accuracy.
With easy to use software, precise alignment protocols and extensive automation capabilities, the system offers a new level of performance and usability.
Speedier lamp testing
Default measuring instrument included in the system is the GL PHOTOMETER 3.0 LS + Flicker which has been designed for On Fly ( non stop ) measurements of automotive and other lamps on goniophotometer.
High sampling rate combined with high sensitivity HAMAMATSU sensor allows for continuous measurement of LED during smooth movement of DUT ( Device Under Test ) Thanks to absolute encoder readings the required data can be obtained in much shorter time.
With this super fast measuring instrument, additional light modulation characterization for turn lights and emergency signals is available using the flicker measurement functionality.
