Type A goniophotometer for photometric measurements in the automotive industry
The continuous development of technology translates into an urgent need to speed up product introduction. This applies to every industry, including automotive lighting manufacturing. The series of tests that vehicle exterior lamps must undergo in the approval process is causing lighting manufacturers to choose to build their own laboratories to reduce the time to market for the final product.
The GL GONIO PHOTOMETER GLG A 50-1800 has been designed in accordance with CIE 121-1996 and IESNA LM-75-01 standards governing photometric and colorimetric far-field measurement systems. It allows the determination of photometric characteristics in H, V coordinates for automotive lamps and headlights as well as all kinds of signaling equipment used, for example, in aviation.
The GL Optic goniophotometer is characterized by its high precision, robust design and user-friendly interface. In cooperation with a photometer, spectrometer and retroreflectometer, it forms a complete system for the automotive industry.
Designers are racing to constantly improve and create unconventional lamps and headlamps. The development of LED technology also contributes to the creation of increasingly unusual solutions. In order to keep up with these developments, testing is necessary at the prototyping stage, preferably in-house in the R&D or QC.
The GLG A 50-1800 goniophotometer can be used in both factory and accredited laboratories. It allows reliable data to be quickly obtained for large and smaller lamps. The design of the goniometer allows the testing of luminaires weighing up to 50 kg and with a diameter of 1800 mm (with an option of up to 2600 mm on special order).
The accuracy of the measurements is guaranteed by 3 motorized axes with absolute encoders. Extensive automation capabilities and intuitive software ensure a new level of productivity.
Faster lamp testing
GL Photometer 3.0 LS + Flicker is a dedicated device for use with a goniometer. It offers the possibility to perform On-fly measurements. During On-fly measurement, the goniometer arm move at a constant speed without stopping, while the photometer takes many thousands of measurements per second to accurately determine the photometric light curve for each plane.
In addition, the flicker measurement function allows the light modulation characteristics of indicators and emergency lights to be determined.

Color measurement also possible
The GL Optic goniophotometric system can be supplemented with a spectroradiometer to extend its functionality to include color measurement. The GL Spectis 1.3 LS is optimized for high-speed measurements of photometric and colorimetric parameters. It is ideal for basic applications and radiation measurements in the visible range.
GL Spectis 5.0 Touch can be used in advanced systems. It also enables spectral analysis outside the visible range (UV-NIR).
