Large-format arrays and high operating temperatures (HOT) are prominent trends in the development of infrared thermal imaging technology. As breakthroughs are achieved in various pixel sizes of megapixel infrared focal plane detectors, Guide Infrared has taken a significant step forward: we have unveiled the world’s first 5-megapixel HOT mid-wave infrared detector at the 2024 China International Optoelectronic Exposition, marking its global debut. This innovative technology marks a significant advancement in the field of infrared thermal imaging, showcasing our commitment to leading the industry.
Pushing the Boundaries of Infrared Detection
The development of large-format infrared detectors has become a key competitive area among industry manufacturers. The newly released 5-megapixel HOT mid-wave infrared detector represents a pinnacle in infrared thermal imaging solutions. This advanced detector features a resolution of 2560×2048 pixels, offering wider field of view and higher coverage, with a pixel size of 10μm. The compact architecture of the device enhances spatial resolution, making it particularly suitable for wide-area and long-distance detection, providing users with unprecedented panoramic detection and situational awareness.
Large-array high-temperature infrared detectors are an important development direction of the third-generation infrared detector technology. As the advantages of thermal imaging components based on such devices in terms of volume, weight, performance and cost continue to emerge, the application prospects of related devices in the field of advanced optoelectronic systems will become broader in the future.
A Leap Forward in Infrared Technology
High-definition imaging requires matching high sensitivity. In standard test conditions, the 5-megapixel HOT mid-wave infrared detector exhibits a noise equivalent temperature difference (NETD) of no more than 20mK. This allows for precise detection of subtle temperature differences and minute target details.
The 5-megapixel HOT mid-wave infrared detector combines high resolution, superior performance, and reliability. It provides four times the pixel count of 1280×1024 detectors, with a full mid-wave spectral response range of 3.7 to 4.8μm, delivering ultra-high-definition infrared images with a broader field of view and more detailed information. This makes it ideal for long-distance detection and fine image recognition.
Advancing Technology with Higher Operating Temperatures
As advanced electro-optical systems increasingly focus on size, weight, and power (SWaP) performance, the demand for compact, low-power, and cost-effective HOT detectors has grown. This trend has made high-temperature operating (HOT) detectors a standard in high-end cooled infrared electro-optical systems, creating new possibilities for large-format arrays. Currently, the 5-megapixel HOT mid-wave infrared detector operates at a focal plane temperature of up to 150K, setting a leading position in its category.
Produced using mature Type-II superlattice material, the 5-megapixel HOT mid-wave infrared detector is amenable to mass production, with excellent product uniformity and stability. Leveraging years of expertise in Type-II superlattice detectors, Guide Infrared has established a stable supply of multiple HOT infrared detector products.
The large-format HOT infrared detector can provide clearer and more detailed infrared images, meeting the high-end infrared application needs of optoelectronic platforms for high dynamics, wide fields of view, and all-weather monitoring. It is suitable for applications in aerospace, border security, and more.
As a leading domestic manufacturer of infrared focal plane detectors, Guide Infrared has established a comprehensive R&D and production system that spans from core infrared devices to integrated optoelectronic systems, ensuring stable mass production and delivery of a wide variety of optoelectronic products. In the future, the company will continue to focus on the forefront of optoelectronic technology, targeting materials and device technology trends, investing in research and development, and maintaining its industry-leading position.
