Core Components of an Endoscope Module

1. Optical Lens Assembly

This is the module's "front-end window," composed of multiple miniature optical lenses. It's responsible for acquiring optical images within the body's cavities and precisely projecting them onto the photosensitive element.

Key performance indicators: Field of view, depth of field, and resolution, directly affecting the observation range and image clarity.

2. Photosensitive Element

This is what you previously knew as a CCD or CMOS sensor, the module's "photosensitive core." It's responsible for converting the light signals transmitted by the optical lenses into electrical signals, a crucial step in image digitization.

In medical applications, disposable endoscopes often use CMOS (low power consumption, controllable cost), while high-end reusable endoscopes commonly use CCD (better image quality, lower noise).

3. Signal Processing Chip

This is the module's "data processor." It's responsible for amplifying, reducing noise, and encoding the electrical signals output from the photosensitive element, converting them into standard digital image signals (such as USB or LVDS signals).

4. Transmission Interfaces and Cables

These interfaces are responsible for transmitting the processed digital signals to the endoscope's display terminal or host. This is the core adaptation scenario in the cable/wiring harness field you are interested in. Commonly used transmission cables include flexible FPC cables, high-shield USB adapter cables, and endoscope handpiece extension cables, which must meet requirements such as miniaturization, high flexibility, anti-interference, and sterilization resistance (reusable modules).
