In dynamic light microscopy applications, imaging specimens from multiple angles while maintaining controlled temperature conditions is crucial for comprehensive and accurate analysis. To address these challenges, we present iCAT, an open-source multifunctional accessory designed to enhance light microscopy. It enables specimen rotation along the axial plane, incorporates built-in modules for precise temperature control, features an integrated LED, and includes a camera for real-time specimen monitoring. It can be easily 3D-printed and assembled using readily available electrical components. Combined with any up-right microscope, this versatile device allows researchers to capture detailed images and videos of organoid cultures and live or fixed specimens, such as C. elegans, zebrafish, drosophila, or mouse embryos. The potential applications of iCAT in investigating dynamic cellular processes and complex developmental phenomena are vast, inspiring researchers to explore its possibilities and push the boundaries of biological research.
