Vega Series

The Vega Technology Series delivers ultra‑stable illumination for precision camera testing at extremely short exposure times. Built on a DC‑driven LED architecture, the series includes Vega for the visible spectrum and Vega IR for 940 nm near‑infrared, enabling contrast‑based performance measurements according to IEEE-2020:2024 across both spectral ranges. The direct‑current LED driver ensures stable output, fine intensity control, and consistent thermal behavior, preventing color shifting and intensity fluctuations. This stability provides the reliability required for accurate CTA, CSNR, and other IEEE-2020:2024 measurements.

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

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

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.

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

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

Vega is designed for high‑precision visible‑light measurements under extremely short exposure times, particularly for automotive HDR cameras.

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.

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

Photometric quantities describe light as perceived by the human eye. They apply only to wavelengths between ~380–780 nm.

• Luminance (cd/m²): perceived brightness of a surface.

• Illuminance (lx): perceived brightness falling onto a surface.

Photometric units weight light using the V(λ) curve, which models human visual sensitivity.

Vega-IR

Radiometric quantities describe physical optical power, independent of human perception. They apply to all wavelengths, including NIR (e.g., 940 nm).

• Radiance (μW/(cm²·sr·nm)): optical power emitted per area, per solid angle, and per nanometer of wavelength.

• Irradiance (W·m⁻²): optical power falling onto a surface.

Radiometric units are essential for IR camera testing because the human eye cannot see IR light, making photometric units meaningless.

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.
