Technical Guide for Endoscope Module Selection

Technical Guide for Endoscope Module Selection

I. Core Parameter Compatibility Analysis

1. Size Matching Assessment

Preferred Applications: Medical lumens (e.g., ureters, paranasal sinuses, periodontal pockets) and industrial conduits (Φ4.0mm+) with target channel diameters of 3.8–5.0mm

Critical Considerations: Evaluate sheath friction resistance for channel diameters 3.5–3.8mm

Inapplicable Scenarios: Flexible applications requiring channel diameters <3.3mm or large-angle bending (>90°)

2. Optical Performance Matching Analysis

Field of View Requirements: 88° FOV suits panoramic cavity observation; pair with optical zoom systems for localized magnification inspection

Working Distance Adaptation: 10-40mm fixed focal length suits close-range observation; select long-focus version for >50mm working distance

Illumination Uniformity: 6-LED ring layout suits 4-8mm diameter channels; <3mm channels may exhibit overexposure

II. Industry Application Adaptation Recommendations

Medical Field Selection Criteria

Sterilization Compatibility: Confirm high-temperature/high-pressure resistance of sheath material for reusable applications

Biocompatibility: Applications involving direct tissue contact must comply with ISO 10993 standards

Operational Ease: 25mm length suits straight endoscopes; flexible applications require bending radius assessment

Key Selection Criteria for Industrial Applications

Environmental Tolerance: Oil-contaminated environments require confirmation of front window lens anti-oil coating

Mechanical Strength: Pipeline inspection requires assessment of front-end impact resistance

Temperature Adaptability: Select temperature-resistant models for high-temperature environments (>60°C).

III. System Integration Technical Requirements

Electrical Interface Compatibility

Recommended image processor support: Minimum 720P@30fps real-time processing.

Power Supply System must provide stable LED drive current (constant current drive recommended).

Signal transmission cable lengths exceeding 1.5m require signal amplification solutions.

Mechanical Integration Solutions

Fixed installations should use M2.5 or larger threaded fasteners

Articulated joint integration requires ±0.3mm positional tolerance allowance

Waterproof applications require O-ring seals (silicone recommended) at connection points

IV. Cost-Effectiveness Optimization Recommendations

Scenarios for downgraded configurations

Routine inspections requiring only standard-definition imaging (480P)

Environments with fixed working distances and adequate illumination

Open inspections with non-critical dimensional requirements

Scenarios Requiring Upgraded Configuration

Applications requiring image measurement or 3D reconstruction

Extreme low-light environments (<10 lux)

Medical applications requiring frequent high-temperature sterilization

V. Validation Testing Recommendations

Mandatory Test Items

Imaging clarity testing under actual working conditions

Stability testing for continuous operation exceeding 4 hours

Performance testing under extreme temperature conditions

Recommended Test Items

Color reproduction accuracy on different tissue/material surfaces

Imaging quality in liquid media

Image stability under vibration

VI. Alternative Solutions

If this module does not fully meet requirements, consider:

Smaller diameter: 2.8mm version (field of view reduced to 75°)

Higher resolution: 2-megapixel version (size increased to 4.0mm)

Zoom version: Supports 15-60mm motorized focus
