AMS Goniometer System
Complete equipment of a light lab for exterior automotive lighting
Exact sample positioning and fast, high-resolution measurement
Automotive lighting is essential for safety and comfort on the road. For the purposes of approval, national and international standards prescribe highly accurate measurement under precisely defined conditions. With its Optronik line, Instrument Systems has developed a tailor-made portfolio of high-quality measuring instruments and systems that have proven themselves over the years in the light channels of international automotive manufacturers.
Based on high-performance AMS goniophotometers Instrument Systems offers high-quality, all-in-one systems for fast, positionally accurate measurement of the spatial radiation properties of external vehicle lighting. Through modular combination of further measuring instruments, the respective system geared to the individual test object and its measurement requirements. Our portfolio includes:
- Photometers for a range of measurement distances
- Tristimulus colorimeters and luminance meters (e.g. for license plate illumination)
Best choice for product approval tests
In their product approval process, many technological leaders in automotive manufacturing worldwide have placed their trust in the accurate and stable measurements produced by this system – particularly for new types of headlight such as pulse-width modulated light sources.
The fully automatic measurements are controlled by the LightCon software, by which all the necessary test reports are prepared.
- Highest positioning accuracy
- High spatial resolution for new functions such as high definition headlamps, pixel headlamps or other ADB variants
- High measurement speed and efficiency
- Conform to the latest standard DIN 5032-7 (2017)
- Pulse-width modulated measurements (PWM concept)
Machine reliability, speed, precision
Due to the safety relevance of the objects to be measured in exterior lighting, strict requirements are imposed on the tests performed on the systems:
- Goniophotometer systems must be extremely robust, durable and reliable, permitting a large number of tests in long-term operation.
- The tests must be performed with a consistently high level of precision with a high measurement speed.
New lighting technologies, e.g. pulse-width modulated light sources or high definition headlamps, also require a conclusive pulse-width modulation concept and a high spatial resolution of the measurement.
