BrightSpot offers customized imaging systems for factory line and robotic integration, offline testing, varied panel orientation and shape, and tight working distance constraints.

Customized Imaging Solutions

Tailored EL, PL, UVF, and Multi-Mode Systems for PV Testing

Not every photovoltaic application fits inside a standard box—and we don’t expect it to. BrightSpot offers customized imaging systems for factory line and robotic integration, offline testing, varied panel orientation and shape, and tight working distance constraints.

Our Customized Solutions

BrightSpot systems can be customized to work with a wide range of different cell and panel architectures.

Optical components can be chosen to work with silicon, thin-films of different band gaps, and to probe different layers in tandem and multi-junction devices.

Our custom solutions have helped many of the 200 companies we have served across the PV value chain, in over 40 countries across the globe.

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.
