System Advantages
Five core advantages building professional microscopy imaging platforms
Complete Ecosystem, Turnkey Delivery
Cameras, lenses, illumination, stands, and software all developed in-house. No need for multi-vendor procurement coordination, plug-and-play saves 60% integration time.
High Resolution + Large Depth of Field
45 MP ultra-clear CMOS + depth compositing algorithms provide micrometer-level depth-clear images within 30 mm field of view.
Multi-band & Low-Light Imaging
Supports white light, near-infrared, and polarization combinations with synchronized exposure of coaxial and ring lights; presents texture details even at 0.05 lux.
Flexible Expansion, Investment Protection
Standard C-Mount and GigE Vision/USB3 Vision protocols enable later upgrades to AI modules, automated stages, and multi-camera synchronization without replacing the main system.
