Vega

The Vega light source is engineered for high‑precision camera measurements at extremely short exposure times, making it ideal for automotive‑grade imaging, HDR sensors, and contrast‑based performance testing. Its DC‑driven LED architecture delivers exceptionally stable illumination, ensuring repeatable CTA and CSNR results even under demanding fast‑exposure conditions.

Vega’s direct‑current intensity regulation eliminates the instability commonly seen in PWM‑controlled systems. By carefully selecting the LEDs and maintaining a thermally consistent operating point, Vega prevents color shifting, intensity fluctuations, and other artifacts that compromise measurement accuracy. The thermal system maintains ±0.5 °C stability, supporting both heating and cooling without drift, even when switching light sources or adjusting intensity.

To support real‑world testing scenarios, Vega provides advanced flicker generation across a wide frequency range, including sine, triangular, and square waveforms. This enables precise evaluation of camera behavior under modulated illumination, a critical requirement for modern automotive imaging systems.

Unlike PWM‑controlled light sources, which modulate intensity by rapidly switching LEDs on and off, Vega regulates intensity through current control, enabling fine‑grained adjustment and high‑intensity output at ultra‑short exposure times. This makes Vega particularly effective for HDR automotive cameras, where illumination stability directly impacts safety‑critical performance metrics.

For applications requiring even higher intensity and stability, explore the Arcturus light source.

DC (direct current) technology does not affect temperature regulation and can achieve temperature stability within 0.5 degee.

Vega's extremely high stability provides a very strong consistency for testing cameras with very short exposure times.

Vega can eliminate color shifting through the meticulous selection of the LEDs.

Advanced low-frequency functionality to include sine, triangular, and square waveforms to cover nearly all real-world scenarios.

Vega has advanced flicker capabilities that can be generated from a wider frequency range.

Measure most of the KPIs from the IEEE-2020:2024 standard, including CTA, CSNR, MMP, and dynamic range.

Vega is an ideal solution for measuring Contrast Transfer Accuracy (CTA), Modulated Light Mitigation Probability (MMP), Contrast Signal-to-Noise Ratio (CSNR), or other high-intensity measurements outlined in the IEEE-2020:2024 standard. These factors are relevant to almost all automotive camera applications, which require test solutions capable of creating dynamic test scenes for cameras with very short exposure times.

Vega is sold with control software that lets you manage up to seven devices simultaneously. APIs are also available (sold separately) to enable seamless integration into individual designs. We offer APIs in C, C++, and Python.

VLS-Evaluation

The evaluation software analyzes the camera's performance using the defined KPIs, including CTA, MMP, and CSNR. CTA evaluations are based on pixel-value distributions. Results are exported as XML files. This software is sold separately.

The TE294 chart is optimized for Vega. It is a unique series of grayscale test charts for high-precision measurements, including Contrast Transfer Accuracy (CTA) and other contrast-based performance indicators. Charts are available individually or in sets. Please note that the TE294 charts are always sold separately from the Vega light sources.

Vega IR Test charts

Vega IR is used with grayscale test charts selected for defined behavior in the near-infrared range. Please contact our sales team to confirm the chart configuration for your wavelengths.

Note:

As with the Vega light sources, you can purchase charts in one-, three-, or seven-piece sets.

The Vega is available in two separate hardware sets. Each set comes with a controller and control software. The controller can connect and control up to seven different Vega light sources. All of which can be programmed with the control software.

The Vega 1+1* is sold with one Vega light source and is perfect for those looking for a simple solution for testing HDR cameras with very short exposure times.

The Vega 3 + 1 Set* includes three Vega light sources and is a great solution for testing camera performance at varying flicker frequencies or for contrast transfer accuracy (CTA) measurements.

In addition to the sets listed above, we also offer individual Vega light sources as an “add-on” option for your project (an “add-on” does not come with a controller or control software).

Please contact our sales department for a consultation if you have questions or inquiries.

*Evaluation software not included.

Arcturus provides extreme illumination levels for challenging HDR sensors, enabling accurate CTA, CNR, and MMP testing in realistic high‑brightness scenes.

Vega IR extends the Vega platform into the near‑infrared band, enabling contrast‑based KPIs for cameras operating under 940 nm illumination (DMS, OMS, RGB‑IR sensors).

The Lightcube‑Controller delivers reliable power management and seamless control for all Vega and Arcturus illumination devices.
