1.6mm OCHFA10 Ultra-Micro USB Endoscope Module: Selection Guide for Extreme Inspection

In advanced fields such as ultra-thin pipeline endoscopy, precision micro-component inspection, minimally invasive medical exploration, and micro-instrument built-in imaging, imaging system selection faces an extreme physical threshold: the probe diameter must be less than 2mm, often as low as 1.6mm to enter micro-catheters, microfluidic channels, or MEMS cavities. When conventional endoscopes are simply too large to enter, a module based on the OCHFA10 Camera Module with a diameter of just 1.6mm, equipped with an ultra-wide angle (H86°/V86°) and USB2.0 UVC driver-free operation, becomes a critical solution for breaking through extreme-space inspection barriers. This article provides a clear selection framework from five dimensions—physical size, optical performance, interface protocol, structural design, and typical applications—while incorporating key terms such as endoscope camera module, OCHFA10 Camera Module, usb endoscope camera, HD Camera Module, 1.6mm Diameter, mini Camera Module, UVC Camera Module, Ultra Wide Angle Camera Module, and CMOS Camera Module to help you precisely match micro-space precision inspection needs.

1. Physical Size: Verifying the 1.6mm Ultra-Micro Probe’s Accessibility

Step 1: Precisely measure the minimum inner diameter and bend radius of the target channel.

The probe diameter is only 1.6mm, representing an extreme miniaturization design among mini Camera Module products. Engineering significance:

• Easily accesses micro-catheters, microfluidic channels, precision mechanism gaps, and natural body orifices with inner diameter ≥1.7mm, covering most “sub-millimeter” narrow spaces in medical, electronics, and micromachinery fields.

• Compared to probes of 2mm or larger, the 1.6mm Diameter extends the detectable range downward by 0.4mm—a small difference that determines whether a 1.8mm medical puncture needle or 1.7mm fiber optic catheter can be accessed.

• The flexible cable design makes the front end extremely small and light, facilitating navigation through tortuous paths, while the rear circuit can be placed away from the inspection area in a handheld device or fixed station.

When selecting, verify: Is the channel inner diameter ≥1.7mm? For sharp 90° bends, evaluate the probe’s rigid section length (typically 3-5mm) and the flexible cable’s bend radius. The module supports custom cable length for different inspection depths.

2. Optical Performance: Ultra-Wide Angle and CMOS High-Definition Imaging

Step 2: Confirm working distance, field coverage, and detail resolution requirements.

This module incorporates the OCHFA10 Camera Module based on CMOS Camera Module technology, providing an H86°/V86° ultra-wide angle field of view (characteristic of an Ultra Wide Angle Camera Module), with distortion < -11%. Key optical value:

• The 86°×86° symmetric field of view achieves extreme field expansion within a 1.6mm diameter, covering a large area at typical working distances of 5-20mm, capturing the entire cross-section of a micro-hole or small pad area in a single frame, effectively reducing probe movement and blind spots.

• Although the sensor resolution is not explicitly stated, the OCHFA10 typically outputs around 700×700 (approximately 0.5MP), making it a lightweight member of the HD Camera Module family, sufficient to clearly reveal 0.05mm-level micro-scratches, foreign objects, solder joint morphology, and micro-structural features.

• Distortion < -11% (barrel) is acceptable in ultra-wide-angle endoscope designs as it expands peripheral vision; for precision measurement, software correction can be applied.

As a practical Ultra Wide Angle Camera Module, this module balances miniaturization and field width. When selecting, assess: If ultra-fine defects below 0.01mm need identification, consider higher resolution solutions (e.g., 1080P), but weigh bandwidth and cost; for most qualitative micro-space inspection tasks, the current configuration is sufficient.

3. Interface and Protocol: Plug-and-Play Advantages of USB UVC Driver-Free

Step 3: Evaluate host platform compatibility and development efficiency.

This module uses a Micro USB-5P interface, incorporates the standard UVC Camera Module protocol, and supports usb endoscope camera plug-and-play without driver installation. Key advantages:

• Cross-platform compatibility: Automatically recognized by Windows, Linux, Android (with OTG), macOS, etc., allowing direct connection to laptops, tablets, or industrial PCs during field inspections.

• Zero driver development: Significantly shortens time-to-market, ideal for medical or inspection equipment manufacturers needing rapid iteration.

• The USB2.0 interface integrates power and signal transmission, simplifying the overall wiring harness.

As a standardized usb endoscope camera, verify that the target host’s USB port provides adequate power (5V/500mA is sufficient); for long-distance transmission (>5m), use active USB extension cables. The module does not include built-in LED illumination; for complete darkness, external micro-LED fill light (via reserved pins on the separate interface) will be needed.

4. Structural and Environmental Adaptability: Flexible Design and Optional Protection

Step 4: Assess installation space and environmental risks.

This module adopts an ultra-small flexible structure, enhancing adaptability to curved paths for flexible deployment in complex narrow spaces. Engineering value:

• The front end is only 1.6mm diameter, allowing passage through extremely narrow channels and sharp bends; the rear circuit can be placed in a handgrip or control box.

• Cable length and diameter are customizable to suit different inspection depths and routing requirements.

• The base version is not waterproof. For wet or liquid-contact applications, consult about custom IP67 Waterproof versions; for dry, clean environments, no special protection is needed.

5. Typical Application Scenarios and Selection Recommendations

6. Selection Decision Summary

The core value of the 1.6mm OCHFA10 ultra-micro USB endoscope module lies in combining the extreme miniaturization of the OCHFA10 Camera Module, the wide coverage of the Ultra Wide Angle Camera Module, the plug-and-play convenience of the UVC Camera Module, the cross-platform compatibility of the usb endoscope camera, and the clear image quality of the HD Camera Module—providing a cost-effective, high-reliability vision solution for ultra-thin pipelines, precision micro-components, minimally invasive instruments, and micro-instruments. When selecting, prioritize three questions:

• How narrow is the space? If channel inner diameter ≥1.7mm, the 1.6mm Diameter probe fits; if smaller, custom an even smaller diameter (feasibility depends on sensor limits).

• Is ultra-wide angle needed? Ultra-wide angle greatly reduces movement, ideal for deep holes or cavities requiring single-pass coverage; for localized detail, a regular field of view may reduce edge distortion.

• How to connect to the host? Standard USB directly connects to computers, tablets, embedded boards; for wireless, add an external USB-to-WiFi module.
