Launching in 2026!
Reach out to our team for more information on the product or a demo of functionality. .
A state-of-the-art portable or fixed measurement system with an integrated spectrometer and pixel calibrated camera engineered to evaluate surface illumination in mobile or fixed environments. Calibration recommended annually.
The HSG Labs 4P is a surface measurement system based on the concept of the Ultimate v3.5 hardware, combining spectral and spatial analysis for calibration and evaluation of RGB laser projectors and LED display systems. This integrated device incorporates a high-resolution spectroradiometer and 20-megapixel imaging sensor, enabling pixel-level measurement analysis and spectral characterization in a single unit.
A full spectral radiometric calibration of the entire sensor chain, giving very high accuracy for all sensors (single point spectrometer or camera full image analysis).
Equipped with a high-performance CPU, the 4P processes large datasets in real time, making it suitable for research, production calibration, and quality assurance workflows. With web UI, designed for field and lab deployment, it supports Ethernet connectivity and integrates easily into automated systems through its open API and SDK support.
