2.0mm OCHFA10 USB Endoscope: Ultra-Micro Module for Precision Inspection

In microfluidic chip inspection, minimally invasive medical device integration, internal observation of precision electronic components, and portable micro-detection equipment development, imaging system selection faces a high physical threshold: the probe diameter must be less than 2.5mm, often as small as 2.0mm to enter target channels. When conventional endoscopes are simply too large to enter, a USB UVC driver-free endoscope module based on the OCHFA10 Sensor, with a diameter of just 2.0mm, 86° symmetric wide angle, and 5–50mm macro focus, becomes a critical option to overcome extreme space inspection barriers. This article provides a clear selection framework from five dimensions—physical size, optical performance, interface protocol, illumination configuration, and typical applications—while incorporating key terms such as endoscope camera module, 700*700/400*400 Resolution Camera Module, usb2.0 endoscope camera, UVC Camera Module, OCHFA10 Sensor, 86° Wide Angle Camera Module, Separate Endoscope, 1080P Camera Module, and IP67 Waterproof to help you precisely match micro-space precision inspection needs.

1. Physical Size: Verifying the 2.0mm Ultra-Micro Probe’s Accessibility

First step: Precisely measure the minimum inner diameter and bend radius of the target channel.

The probe diameter is only 2.0±0.05mm with a separate design (Separate Endoscope), where only the lens and sensor are at the front end, connected to the rear circuit via a 1.5-meter flexible cable. Engineering significance:

• Easily accesses micro-catheters, microfluidic channels, precision mechanism gaps, and natural body orifices with inner diameter ≥2.2mm, covering the vast majority of “sub-millimeter” narrow spaces.

• Compared to conventional endoscopes of 3mm or larger, 2.0mm extends the detectable range significantly downward, making previously invisible microstructures clearly visible.

• The separate structure makes the front end extremely light, and the rear circuit can be placed in a handheld grip for ergonomic operation.

When selecting, verify: Is the channel inner diameter ≥2.2mm? For sharp 90° bends, evaluate the probe’s rigid section length (typically 3-5mm) and cable bend radius. The module supports custom cable length and diameter for different deployment environments. For wet or liquid-splash scenarios, an IP67 Waterproof steel shell version is available to enhance durability.

2. Optical Performance: 86° Symmetric Wide Angle and 5–50mm Macro Focus

Second step: Confirm working distance, field shape, and detail resolution capability.

This module incorporates the OCHFA10 Sensor, typically outputting 700×700 or 400×400 resolution, configurable as a 700*700/400*400 Resolution Camera Module. Its 86°×86° symmetric field of view is characteristic of an 86° Wide Angle Camera Module, providing a square imaging frame that reduces blind spots for both square and circular targets, especially suitable for microchannels and solder joint arrays. Key optical parameters:

• 5–50mm dedicated macro focus: Combined with 0.418mm focal length, precisely covering typical endoscopic working distances from ultra-close (5mm) to medium range (50mm) without frequent refocusing.

• 86° symmetric wide angle: covers about 18mm of field width at 10mm working distance, capturing the entire cross-section of a micro-hole or a small pad area in a single frame.

• Resolution options: 700×700 provides near-0.5MP detail for higher clarity (e.g., micro-crack identification); 400×400 offers smaller data volume for real-time smooth preview or low-power embedded systems.

As a flexible 700*700/400*700 Resolution Camera Module, this module allows users to choose based on bandwidth, storage, and display resolution matching. Compared to chasing super-high pixels of a 1080P Camera Module, the OCHFA10 Sensor achieves balanced detail and light sensitivity within a 2.0mm diameter, making it more suitable for portable mobile devices.

3. Interface and Protocol: Plug-and-Play Advantages of USB2.0 UVC Driver-Free

Third step: Evaluate host platform compatibility and development efficiency.

This module uses a Micro USB 5P interface, incorporates the standard UVC Camera Module protocol, and is plug-and-play without driver installation. As a usb2.0 endoscope camera, its core advantages include:

• 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.

• Separate design: the rear circuit directly outputs via USB, simplifying overall device design.

When selecting, verify: Does the target host’s USB port provide adequate power (5V/500mA is sufficient)? For long-distance transmission (>5m), use active USB extension cables or fiber optic solutions. The module includes 4 integrated LED lights, eliminating the need for external illumination.

4. Illumination Configuration and Environmental Protection: Dark-Field Adaptability and Optional Waterproofing

Fourth step: Assess ambient lighting conditions and liquid/dust risks.

This module comes standard with 4 integrated white LEDs providing uniform front fill light, ensuring clear imaging even in complete darkness. For highly reflective metal or different material surfaces, brightness can be adjusted via an external PWM signal (requires additional driver design). Engineering value:

• No external light source needed – ready to use, suitable for portable devices.

• Low-power LEDs work with USB 5V supply, keeping total power low and extending battery life.

• Optional IP67 Waterproof rating: Steel shell sealing provides dust protection and temporary immersion resistance, suitable for wet pipes, medical disinfection, and outdoor scenarios.

Note: The base version is not waterproof. For liquid-contact applications (e.g., endoscope disinfection, sewer inspection), be sure to select the IP67 Waterproof custom version. The steel shell also provides impact protection.

5. Typical Application Scenarios and Selection Recommendations

6. Selection Decision Summary

The core value of the 2.0mm OCHFA10 ultra-micro USB endoscope module lies in combining the extreme miniaturization of a Separate Endoscope, the symmetric wide field of an 86° Wide Angle Camera Module, the plug-and-play convenience of a UVC Camera Module, the flexible resolution options of a 700*700/400*400 Resolution Camera Module, the environmental protection of IP67 Waterproof, and the 5–50mm macro focus – providing a cost-effective, high-reliability vision solution for micron-level pipeline inspection, precision micro-component observation, and portable minimally invasive medical devices. When selecting, prioritize three questions:

• How narrow is the channel? If inner diameter ≥2.2mm, the 2.0mm probe fits; if smaller, custom an even smaller diameter (feasibility depends on sensor limits).

• What resolution is needed? For detail, choose 700×700; for smoothness and low power, choose 400×400.

• Is waterproofing or high reliability needed? For wet or liquid-contact environments, IP67 Waterproof is mandatory; for dry scenes, the standard steel shell version reduces cost.
