Product Introduction

The MEAGLE 320-PRO is a laser‑scanning confocal microscope independently developed and manufactured by Changyi Guangke. It matches the performance specifications of imported confocal systems, offering a high‑performance, cost‑effective alternative among domestic brands. The MEAGLE 320-PRO delivers an ultra‑high resolution of 8192 × 8192 pixels, with a standard imaging speed of 12 fps; when paired with a resonant scanning galvanometer, its frame rate can reach up to 32 fps. Equipped with proprietary algorithms for spectral scanning and spectral unmixing, it achieves continuous spectral tuning with an accuracy of 1 nm. Behind the fully domestically produced components and software lies outstanding performance that meets or exceeds the key benchmarks of leading international brands.

The MEAGLE 320-PRO offers a wide range of imaging modalities, supporting bright-field imaging, wide-field fluorescence imaging, TIRF‑wide-field imaging, and more. It can be optionally equipped with a spinning-disk confocal system and features multiple high‑precision motion stages, enabling motorized focusing, three‑dimensional scanning, and automated large‑field‑of‑view stitching, among other imaging capabilities. Its advanced post‑processing analysis bridges the gap between qualitative and quantitative observations; the system provides an extensive suite of post‑processing tools, including deconvolution, image enhancement, image smoothing, morphological processing, and feature segmentation, while also offering specialized analytical functions such as cellular statistical analysis, subcellular localization, protein colocalization, forward and reverse tracking, cell subpopulation classification, and cell tracking.
