Overview

The Rigsters LightArray is a precision flash LED lighting system engineered for advanced photometric capture and for generation of high-fidelity physically based rendering (PBR) texture maps. Leveraging high-intensity COB LED modules with a CRI of 95+ and a TLCI of 99+ coupled with a 60° aspherical lens, LightArray delivers uniform beam distribution and exceptional light quality. Designed to minimize manual post-processing, the system enables rapid, individually controlled flash sequences and dynamic polarization state changes, ensuring detailed capture of surface textures and reflectivity properties. Whether deployed as a stand-alone kit or integrated with the Arago system, LightArray offers versatile and reliable performance for both industrial and creative imaging applications.

Intended Use

LightArray is intended for professionals and advanced imaging users who require precision lighting control for photometric analysis and the creation of accurate PBR texture maps. Typical use cases include:

• Product Visualization & Quality Control: Achieving detailed and consistent surface capture.
• Creative Imaging: Supporting high dynamic range and fine-detail capture for visual effects and digital content.

Users should operate LightArray in a controlled environment, following all safety guidelines and handling protocols. The system integrates seamlessly with camera tethering solutions and supports major camera brands such as Nikon, Canon, and Sony, ensuring a smooth workflow from capture to post-processing.
