BrightSpot integrates hardware components (specialized camera, EL/PL power supply, PL Lamps, and optional filter wheel) with its IMPEL software for device control as well as image capture and processing. Recipes make it easy to replicate camera and power supply parameters as well as image contrast enhancement and cropping.

Whether you’re testing next-gen tandem cells, working in a space-rated clean room, or need custom optics for your line, we can help. BrightSpot has built custom EL, PL, and UVF systems for some of the most demanding PV applications on Earth—and in orbit.
Contact us and discuss your needs with one of our experts.
Uses safe green or red LED light sources and a high resolution PL camera within a lightproof enclosure, to obtain contactless images of partially and fully processed cells and minimodules; Non-contact PL imaging can even be applied to partially processed cells, while comparing EL to PL images allows the user to differentiate between series-resistance and bulk/surface quality effects.
Inject current via clipping to wires, probing pads, chuck busbar probing, or multiplexed probing of arrays of thin-film cells
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.
