Compact and Precision: MindVision MV-MS136GC-M Coaxial Camera Solves Narrow Space Inspection Challenges

As machine vision technology evolves towards precision, miniaturization, and high efficiency, the demand for narrow space inspection scenarios is increasingly prominent — from the identification of tiny defects in LED mounting, to the precise monitoring of semiconductor welding, from the internal condition detection of small equipment, to the dynamic imaging carried by robotic arms. Traditional industrial cameras struggle to meet scenario-specific needs due to their large size, complex wiring, and poor adaptability. As a leading enterprise in China's industrial camera industry, MindVision has deeply cultivated core machine vision technologies and independently developed the MV-MS136GC-M series coaxial cameras. With the core advantages of "ultra-small size, high-performance output, and easy deployment", it breaks through the bottleneck of narrow space inspection, providing efficient and reliable imaging solutions for electronic manufacturing, semiconductors, precision assembly and other industries, demonstrating the technical strength and innovative value of domestic industrial cameras.

Known as the "miniature smart eyes" in machine vision systems, coaxial cameras’ core advantage lies in balancing compact structure with high-definition imaging, enabling precise perception in limited spaces. Their technical thresholds focus on three dimensions: size control, performance balance, and scenario adaptation. Relying on a professional R&D team of nearly 300 people and years of practical experience in industrial scenarios, MindVision has comprehensively optimized the MV-MS136GC-M series coaxial cameras. It not only retains the accuracy of coaxial imaging, but also breaks through the performance limitations of traditional products, becoming the preferred equipment for narrow space inspection scenarios.

Ultra-Miniaturized Design, Adaptable to Various Narrow Scenarios

To address the core pain points of "difficult installation and poor adaptation" in narrow space inspection, the MV-MS136GC-M series coaxial cameras adopt an ultra-lightweight and miniaturized design, controlling the overall size to 14*14*48mm, with a module cross-section of only 11.5*11.5mm. The compact structure without lens mount and rear shell interface allows it to be easily embedded in areas inaccessible to traditional cameras, such as the interior of various small equipment and narrow assembly gaps. At the same time, the overall weight is ≤20g, and its lightweight feature enables stable mounting on robotic arms for mobile inspection, without worrying about additional load affecting the operation accuracy of robotic arms, adapting to the flexible needs of dynamic inspection scenarios.

In terms of interface design, this series of cameras supports M12 lenses, paired with threaded interfaces (M12*0.5 / 1/4-36UNS), which are firmly installed and easy to disassemble. Adaptive lenses can be replaced according to different inspection needs, further expanding the scenario coverage. Whether it is a narrow inspection station on an LED mounting production line or a precise monitoring point for semiconductor welding, the MV-MS136GC-M can achieve "seamless adaptation and stable imaging", completely solving the problem that traditional cameras "cannot be installed or used conveniently".

Integrated Wiring + High-Performance Output, Balancing Efficiency and Precision

In narrow space inspection scenarios, complex and messy wiring not only affects inspection efficiency, but also may interfere with the normal operation of equipment. The MV-MS136GC-M series coaxial cameras innovatively adopt an "integrated single-line" design. A single camera only needs one line to simultaneously realize three functions: image transmission, trigger control, and power supply. This greatly simplifies wiring requirements, reduces on-site deployment difficulty, and effectively avoids signal interference caused by messy wiring. The maximum transmission distance can reach 15 meters, meeting the wiring needs of long-distance inspection scenarios.

In terms of imaging performance, this series of cameras does not compromise. Equipped with MindVision's independently developed CMOS sensor, it provides two versions: color (MV-MS136GC) and monochrome (MV-MS136GM), with an optical size of 1/4" and a pixel size of 2.7umx2.7um. Combined with global shutter mode, it can effectively eliminate motion blur during high-speed shooting, ensuring clear and stable imaging. The resolution of 1.3 million pixels (1080x1280), paired with a high frame rate of 120fps for a single camera, can accurately capture tiny defects and dynamic processes; even when 12 cameras input simultaneously, the frame rate can still reach 70fps, meeting the high-efficiency needs of multi-station synchronous inspection and greatly improving production line inspection efficiency.

To further ensure imaging quality, the MV-MS136GC-M series cameras have optimized core performance parameters: AD width reaches 12bit 40dB, signal-to-noise ratio (SNR) is 66dB in linear mode, and SNR > 100dB in wide dynamic mode. The excellent dynamic range can clearly present the details of inspection targets in complex lighting environments; the sensitivity reaches 7120mV/lux·s (color) and 8250mV/lux·s (monochrome) respectively, with excellent quantum efficiency, enabling high-quality imaging even in low-light environments, adapting to low-light inspection scenarios such as semiconductor welding. In addition, the camera supports 3D noise reduction, ISP image processing acceleration and other functions, which can effectively suppress image noise, improve the accuracy of defect identification, and reduce the false judgment rate.

Flexible Expansion + Comprehensive Adaptation, Empowering Precision Inspection in Multiple Industries

The MindVision MV-MS136GC-M series coaxial cameras not only have excellent single-machine performance, but also strong expansion flexibility. Equipped with a 12-channel independent channel capture card, each camera can set parameters independently and support batch settings. It can flexibly expand the number of cameras according to the inspection needs of the production line, adapt to multi-station and multi-dimensional synchronous inspection scenarios, and greatly reduce the cost of system upgrading and expansion.

In terms of software and system adaptation, this series of cameras is fully compatible with Windows XP/7/10/11 32/64bits and Linux32/64bits operating systems. The SDK supports mainstream machine vision software platforms, enabling rapid integration without additional drivers, simplifying the secondary development process and shortening the project landing cycle. The camera supports various functions such as arbitrary size ROI custom resolution, contrast adjustment, white balance correction, and custom dead pixel coordinate correction. It can flexibly adjust imaging parameters according to the needs of different inspection scenarios to achieve personalized inspection adaptation.

With its compact structure, high-performance imaging and flexible adaptability, the MV-MS136GC-M series coaxial cameras have been widely used in many core industries: in the LED mounting field, it is used to detect defects such as mounting offset and cold solder joints; in the semiconductor field, it monitors the precision of the welding process and identifies tiny welding defects; in the small equipment manufacturing field, it is embedded in the equipment to detect the assembly precision and appearance quality of components; in the robotic arm application field, it is mounted at the end of the robotic arm to achieve mobile and precise dynamic inspection, comprehensively empowering the upgrading of industrial precision manufacturing.

As a national high-tech enterprise, MindVision has always focused on "independent R&D and quality first". Its products have passed authoritative certifications such as CE and RoHS, and strictly follow global industrial standards to ensure the stability and reliability of product quality. The launch of the MV-MS136GC-M series coaxial cameras is not only another innovative achievement of MindVision in the field of miniaturized industrial cameras, but also a vivid manifestation of domestic industrial cameras breaking technical barriers and achieving precise empowerment.
