The Vega light source provides a solution for high-precision measurements at very short exposure times, as seen in automotive-grade cameras. Vega uses LEDs driven by DC (direct current) technology, making it one of our most sophisticated and unique light sources ever developed.
Cameras with very short exposure times often experience stability problems due to inadequate testing devices. Vega's extremely high stability provides a previously unattainable consistency for measuring these types of cameras.

While we use DC technology for this device, we can eliminate color shifting by carefully selecting the LEDs. The DC driver does not affect temperature regulation, and we can achieve temperature stability within 0.5 degrees. The temperature system works both ways (i.e., heating and cooling) and will remain consistent even when turning on/off different light sources or changing the intensities.
Vega also has advanced flicker capabilities and can be generated from a wider frequency range. We have also further developed the low-frequency functionality to include sine, triangular, and square waveforms, which allows us to cover nearly all real-world scenarios.
Why Vega?
Unlike PWM-controlled light sources, where intensity is regulated by the high frequency of switching LEDs on/off, Vega regulates intensity by the amount of current and offers very fine adjustment. These features allow the Vega to measure high intensities with extremely short exposure times. HDR cameras from the automotive sector benefit greatly from this technology as they require the highest level of performance to ensure safety.
