1. Digital Microscopy Upgrade (No PC Needed)
Scenario: Upgrading traditional optical microscopes to digital without adding a bulky computer tower.
The Advantage: Connect the UC-678 directly to a 27-inch 4K monitor. The STARVIS 2 sensor reveals details in dark biological samples (fluorescence) that standard cameras miss, and the 60fps (at 1080p) ensures no motion blur when moving the slide.
2. Dental & Surgical Documentation
Scenario: Dentists need to show patients live video of their teeth on a chair-side monitor.
The Advantage: The high color fidelity and dynamic range of IMX678 ensure gum tissue and enamel colors are accurate. The HDMI connection is reliable and doesn't crash like Windows drivers often do.
3. PCB Soldering & Repair Station
Scenario: Technicians repairing smartphones under a magnifier need to look at a screen instead of hunching over.
The Advantage: The "Zero Latency" is critical here. If the video lags, the technician might burn the board with the soldering iron. This camera provides instant visual feedback.
Industrial Inspection & Quality Control
