Core Principle
While standard endoscopes use color (Bayer-filter) sensors, the monochrome configuration removes this filter and pairs the sensor with dedicated Infrared (IR) LEDs.
Key Advantages
Superior Sensitivity: No filter obstruction allows maximum light capture, yielding cleaner, lower-noise images in low-light conditions.
Higher Effective Resolution: Eliminates color interpolation, delivering the sensor's true native resolution for sharper spatial detail.
Enables Functional Imaging: Utilizes Near-Infrared (NIR) light for fluorescence imaging (e.g., using ICG dye to highlight blood flow, tumor margins), providing physiological data beyond visible light.
Key Disadvantages
Lacks Color Information: Cannot provide intuitive color assessment of tissue (inflammation, bleeding), rendering it unsuitable for general diagnostic examination.
Specialized Application: Higher system cost is justified only for specific NIR fluorescence or high-sensitivity use cases.
Requires System Integration: Typically needs to be combined with a standard color endoscope in a "dual-mode" system, increasing complexity.
Conclusion
The monochrome + IR module is not a replacement for color endoscopes. It is a specialized, high-performance tool designed for surgical guidance and advanced imaging, trading color vision for ultimate sensitivity and the ability to visualize hidden physiological processes.
