BrightSpot was greatly helpful in designing and implementing custom stress tests to demonstrate the imperviousness of our marine solar panels to cell cracking, and their PanEL-Spot system works beautifully. In the coming months, we plan to implement their EL camera system into our production line.

IMPEL Software

Control

IMPEL is the unified control platform for BrightSpot imaging systems, enabling seamless coordination of camera, light sources, and power supply. From a single interface, users can adjust exposure settings, trigger PL or EL sequences, and automate capture workflows across multiple system components.

Enhancement

Built-in image processing tools help users sharpen contrast, highlight defects, and visualize subtle variations in cell or panel performance. With support for custom filters and multispectral imaging, IMPEL ensures every captured frame delivers actionable insights, whether in R&D or field diagnostics.

Report

IMPEL simplifies documentation by generating detailed reports with embedded images, metadata, and measurement context. Export results for internal QA, client acceptance, or long-term traceability – standardized and ready to share.
