Vega IR

Vega IR extends the Vega platform into the 940 nm near‑infrared range, delivering high‑stability DC‑driven LED illumination for contrast‑based camera performance testing. Designed specifically for IEEE-2020:2024 measurements, Vega IR enables accurate Contrast Transfer Accuracy (CTA) and Contrast Signal‑to‑Noise Ratio (CSNR) evaluation under NIR illumination, matching the precision and stability of the visible‑light Vega system.

Vega IR operates at 940 nm, the dominant wavelength used in automotive driver monitoring systems (DMS), occupant monitoring systems (OMS), and RGB‑IR cameras. To assess how well these cameras resolve contrast under their own infrared light, the illumination source must reproduce the camera’s operating wavelength with high accuracy and stability, exactly what Vega IR is engineered to provide.

Because infrared light lies outside human visual sensitivity, NIR intensity cannot be described using photometric units such as cd/m². Vega IR is therefore radiometrically characterized, ensuring that CTA and CSNR measurements rely on defined radiance rather than visible‑light equivalents. This guarantees physically correct and repeatable NIR test results.

Built on the same DC‑driven LED architecture as Vega, Vega IR offers fine intensity control, high output stability, and consistent thermal behavior even at extremely short exposure times. The DC driver maintains the operating point without affecting temperature regulation, allowing the device to remain stable when switching sources or adjusting intensity. Vega IR also includes the platform’s advanced flicker generation, supporting sine, triangular, and square waveforms, essential for testing cameras that rely on modulated infrared illumination.

Looking for the visible‑light version? See our Vega light source.

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.

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

In addition to the set 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).
