What is a good solution for engineers and professionals to make ultra clear and fine enough line indication for all industrial inspection works? It is not simply relying on any prior line drawing or printing work under all night version illumination fields, however, it would be a better solution to apply a long wavelength made device of a 980nm infrared line laser module. Being made with an import 980nm infrared laser diode, it projects invisible infrared laser light to the human eyes, does not interfere with the inspection environment. The projected IR laser light from a infrared laser line generator enables no visible light, non glaring, non reflective, and does not affect on-site lighting or manual operation, suitable for long term continuous industrial inspection.
Owing to its invisible infrared light emission, 980nm infrared line laser module enables high spectral matching with mainstream CCD/CMOS industrial cameras, ensuring sharp and uniform straight line imaging, significantly improving the recognition accuracy and stability of vision algorithms. Being made with a qualified glass coated lens within 10 to 110 degree fan angles, it enables a highly straight infrared reference line with clear edges, uniform energy distribution, no breaks, meeting the requirements for micron-level high-precision inspection. When infrared laser line generator is operating under harsh occasions, near infrared laser light has superior penetration compared to visible light, ensuring stable projection even in harsh industrial environments such as oil, dust, and water mist, minimizing the impact of external environmental factors on detection.
In various industrial inspection fields, under operation with correct output power and optic lens fan angle, 980nm infrared line laser module makes non-contact, wear free IR line projection, suitable for non-destructive testing of precision parts, soft materials, high-temperature workpieces, and fragile items, protecting product surface quality. It allows for 24 hours continuous operation, low optical power drift, long lifespan, and meeting the 24/7 online inspection needs of factories. Being made with ultra compact size, this infrared alignment laser allows for easy integration and easy installation, owing to its freely selected line thickness and line length, it allows for quick integration into automated inspection equipment, machine vision systems, and specialized inspection fixtures.
Applications in industrial inspection fields:
Machine Vision Dimension Inspection. As a high-precision visual reference line, infrared laser line generator works with industrial cameras to automatically measure the dimensions, thickness, spacing, and aperture of workpieces. It is widely used in online full inspection and sampling inspection of 3C electronics, hardware, plastics, and automotive parts.
Contour and Deformation Detection. Through one-line structured light projection, it performs contour scanning, flatness detection, and curvature and warpage analysis on curved surfaces, sheet metal, die-cast parts, and irregularly shaped parts, achieving rapid 3D morphology reconstruction and defect identification.
Surface Defect Detection. Infrared alignment laser is used for identifying surface defects such as scratches, cracks, dents, bubbles, burrs, and dirt, enabling high-speed, non-contact defect capture on continuous production lines for metals, glass, films, and sheets.
