Micro Endoscope Camera Module Selection Recommendations: Using the GC5035 High-Performance Module as an Example

When selecting a camera module for your medical or industrial endoscopy equipment, it is essential to strike the optimal balance between performance, size, cost, and application scenarios. The following key selection criteria and recommendations are based on the current mainstream 5-megapixel GC5035 module, aiming to assist you in making an informed decision.

1. Core Selection Criteria Analysis

Image Performance Dimension: Resolution and Image Quality

Selection Recommendation: The GC5035 module analyzed here delivers 5MP (2592×1944) high-definition resolution. If your application primarily involves lesion screening, high-definition image archiving, or precise surgical navigation (e.g., minimally invasive surgery, tissue biopsy), 5MP delivers richer detail and is the preferred choice. For routine positioning observation, process verification, or spatial exploration, consider lower-cost 2MP or lower-resolution solutions.

Structure and Integration Dimensions: Size and Illumination

Size: With an outer diameter of Φ7.0mm, this module features an ultra-compact design. This size is critical for devices intended for pediatric use, ultra-thin diameters, or passage through complex, narrow lumens. For standard adult endoscopes, Φ8-10mm modules may offer greater structural strength or broader sensor options.

Illumination System: The integrated 6 LEDs represent a key highlight of this module, addressing the core challenge of uneven illumination within cavities. For inspections of deep or dark cavities (e.g., digestive tracts, industrial pipelines), multi-LEDs with high uniformity are essential for enhancing diagnostic/inspection quality. If the application environment is well-lit or the inspection site is superficial, the number of LEDs can be reduced as appropriate to optimize power consumption and heat dissipation.

Optical Performance Dimension: Field of View and Depth of Field

Field of View: The 82° (D) wide-angle field of view is ideal for observing large areas of tissue or structures without frequent lens repositioning, minimizing visual blind spots. For pinpoint, magnified examination of specific microscopic lesions, consider configurations with a slightly narrower field of view but higher resolution.

Depth of Field: The 30-80mm depth of field range ensures clear imaging of objects within this distance without frequent refocusing. This is highly suitable for scenarios with rapid distance changes or variable working spaces (e.g., instrument movement during surgery). For fixed operating distances (e.g., certain industrial inspections), a fixed-focus solution with a narrower depth of field but optimized optical performance may be preferred.

2. Scenario-Based Selection Roadmap

High-End Diagnostics & Surgical Navigation:

Recommended Configuration: 5MP high resolution + 6 LED uniform illumination + wide-angle medium depth of field.

Rationale: Requires highest image quality for diagnosis, ample illumination ensures color fidelity, wide-angle facilitates overall field-of-view observation, moderate depth of field maintains image clarity during instrument movement.

Routine Endoscopy and Screening:

Recommended Configuration: 2-5MP resolution + 4-6 LED illumination + standard field of view.

Rationale: Balances cost and performance, ensures image clarity meets baseline diagnostic requirements, illumination sufficiently covers primary observation areas.

Industrial Piping and Precision Inspection:

Recommended Configuration: Prioritize illumination uniformity and structural reliability. Opt for industrial versions with scratch-resistant lenses and oil-repellent coatings. Resolution should align with defect detection precision requirements.

Reasoning: Complex industrial environments involving oil, moisture, or friction demand equipment durability and environmental adaptability over maximum resolution.

3. Critical Validation Tips

Before final selection, strongly recommend the following verifications:

Prototype Testing: Evaluate imaging performance, thermal behavior, and power consumption in simulated real-world conditions (e.g., phantoms, simulated cavities).

System Compatibility: Confirm module interfaces (e.g., MIPI) and power supply voltages (3.3V/5V) are fully compatible with your host platform.

Supplier Support: Evaluate the supplier's ability to provide stable mass production supply, customization services (e.g., adjusting FOV, LED color temperature), and necessary technical documentation support.

4. Conclusion

The 5MP, 6-LED, Φ7.0mm wide-angle endoscope module represented by the GC5035 is an ideal choice for applications demanding high-definition image quality, superior illumination, and extreme miniaturization. It is particularly suited for high-end medical diagnostics and minimally invasive surgery where image detail and field of view are paramount.

Your final selection should begin with clearly defining your core requirements: Is “wide field of view” more critical than “high image clarity”? Or does “stability and reliability” take precedence over “extreme specifications”? Clarifying this question will help you pinpoint the most suitable module for your product among the vast array of options available.
