How Micro CMOS Sensors are Changing Video Borescopes

March 13, 2025

The development of micro CMOS sensors is ushering in a new era of precision for industries requiring high-performance inspection tools. Companies like Hawkeye Borescopes are at the forefront of this innovation, with the introduction of Micro Q2 video borescopes that are start under 1mm in diameter.

Here’s a deeper dive into how these new sensors are changing the landscape:

What Are Micro CMOS Sensors?

Micro CMOS (Complementary Metal-Oxide-Semiconductor) sensors are tiny, efficient imaging devices capable of producing high-resolution video output. Unlike traditional borescope sensors that use larger sensors, micro CMOS sensors are more compact, consume less power, and generate less heat. These advancements in sensor technology have enabled the production of borescopes that can fit into previously inaccessible spaces.

The Evolution of Video Borescopes

Video borescopes, traditionally used for industrial inspections, are now benefiting from the miniaturization offered by micro CMOS technology. In the past, inspection tools with video capabilities could only reach certain sized cavities or components. However, as these sensors have become smaller and more efficient, manufacturers like Hawkeye have developed ultra-narrow borescopes (as small as 0.95mm in diameter) that can navigate intricate, hard-to-reach spaces with ease.

How Micro CMOS Sensors Are Changing the Game

1. Increased Miniaturization:
   • Compact Size: The most noticeable change is the significant reduction in size. Traditional video borescopes have limitations on their diameter, but with micro CMOS sensors, even under 1mm, these tools can now access previously unreachable areas. The small size allows them to inspect confined spaces with ease, such as microelectronics, tiny mechanical parts, or even the intricate inner workings of medical devices.
2. High-Resolution Imagery:
   • Enhanced Clarity: Despite their small size, micro CMOS sensors can deliver up to eight times the resolution of older fiber borescopes, improving image clarity. This is essential in inspections where even the smallest defect could have major implications. For instance, in aerospace or automotive applications, identifying microscopic cracks or wear patterns could prevent costly failures.
3. Improved Flexibility:
   • More Versatile Designs: Thanks to the miniaturization, these sensors can be used in highly flexible, thin probes that bend and maneuver in ways that traditional borescopes could not. This opens new possibilities for inspecting complex components and systems that have irregular shapes or small entry points.
4. Enhanced Lighting Solutions:
   • Built-in LED Illumination: Even with a small form factor, the integration of high-powered LED lighting ensures that the smallest spaces are well-lit for clear inspection. The lights, often built directly into the sensor housing, prevent shadows or dark areas from obstructing the view, ensuring better quality images even in tight or dim spaces.
5. Increased Durability and Efficiency:
   • Longer Lifespan and Low Power Consumption: CMOS technology is known for its robustness and efficiency. These sensors offer low power consumption while maintaining excellent durability, making them ideal for extended use in industrial environments where uptime and reliability are crucial.

Industries Benefiting from Micro Borescopes

The ability to inspect smaller spaces with higher detail benefits a wide range of industries. Here are just a few:

1. Aerospace:
   • In aerospace, maintaining the safety and efficiency of aircraft is paramount. Micro Q2 borescopes can inspect engine parts, turbines, and hard-to-reach areas within aircraft, ensuring there are no cracks or signs of wear that could lead to failures. This allows for preventative maintenance that reduces the risk of in-flight issues.
2. Automotive:
   • In automotive manufacturing and repair, these tools are invaluable for inspecting intricate engine components like fuel lines, sensors, and even catalytic converters. With such a compact inspection tool, manufacturers can perform quality control checks and ensure components meet the highest standards before assembly.
3. Medical Devices:
   • The medical industry has strict standards when it comes to the functionality and integrity of its equipment. With micro video borescopes, manufacturers can inspect the interiors of surgical instruments, diagnostic devices, and implants to ensure they are free of defects, foreign bodies, or contaminants.
4. Electronics Manufacturing:
   • Electronics manufacturing requires extreme precision, particularly in inspecting tiny circuit boards, microchips, and internal components of electronic devices. These micro borescopes can navigate the smallest cavities in electronics to ensure there are no defects, helping to maintain the quality and reliability of products like smartphones, computers, and medical devices.
5. Oil and Gas:
   • In the oil and gas industry, inspecting pipes and machinery that are often located deep underground or underwater requires specialized tools. Micro video borescopes equipped with CMOS sensors are ideal for these inspections, enabling real-time data on pipe conditions, avoiding costly shutdowns or repairs.
6. Energy and Utilities:
   • Power plants and utility companies often require inspection tools that can safely enter restricted or hazardous areas. Micro borescopes with advanced CMOS sensors allow for the assessment of turbines, valves, and reactors without the need for disassembly, improving safety and efficiency.

The Future of Micro Borescope Technology

As micro CMOS sensor technology continues to advance, the potential for even smaller, more powerful inspection tools is limitless. Innovations such as wireless connectivity, better imaging software, and more robust probes are expected to emerge, offering even more capabilities for industries around the world. As demand for miniaturization and precision continues to rise, industries will increasingly rely on these small, efficient tools to maintain safety, quality, and efficiency.

Conclusion

The evolution of micro CMOS sensors is significantly transforming the world of video borescopes. With the ability to create borescopes as small as 0.95mm in diameter, companies like Hawkeye Borescopes are leading the way in providing high-resolution, efficient, and versatile inspection solutions. Whether in aerospace, automotive, or medical fields, these micro video borescopes are setting new standards for precision, flexibility, and reliability, allowing industries to inspect hard-to-reach areas with unmatched clarity and confidence.
