When highly precise dot measuring works is processing under all types of industrial inspection work fields, not able to rely on any visible laser device or manual dot work at all, it would be a much better solution to apply a long wavelength made device of a 980nm infrared laser diode module. It emits invisible infrared laser beam from an import 980nm infrared laser diode. Basically infrared laser dot is used as a reference mark, it is used in processes such as mechanical assembly, circuit board welding, and component bonding to assist workers or automated equipment in achieving high-precision positioning and ensuring that process errors meet standards.

Compared to any other visible laser devices, the genuine use of a 980nm infrared laser diode module is projecting invisible infrared laser beam and infrared reference dot from beam aperture. It can make efficient defect detection and identification. By utilizing the differences in the penetration and reflection of infrared light to different materials, it illuminates the surface of workpieces such as metals and plastics. Combined with infrared imaging equipment, 980nm infrared dot laser identifies minute defects such as surface cracks, scratches, and dents. When it projects highly powerful and intense infrared laser light source, cooperated with adjustable focus optic lens in front of beam aperture and low laser beam divergence of less than 0.5mrad, it forms micron-level fine light spots, meeting the positioning and micro-defect detection needs of precision components.

In practical industrial inspection work fields, 980nm infrared laser diode module gets strong environmental stabilization. 980nm infrared laser light is unaffected by visible light or strong light (such as workshop lighting or sunlight), ensuring stable operation even in complex lighting environments and guaranteeing accurate detection results. Being used as the emitting unit of a laser rangefinder sensor, 980nm infrared dot laser alignment calculates dimensional parameters such as workpiece thickness, spacing, and height based on the time difference of light spot reflection. It is suitable for online real-time measurement and quality control.

Any time 980nm infrared laser diode module gets correct use of output power and operating voltage DC power supply, it exhibits excellent reflection or penetration response to various industrial materials, including metals and non-metals, offering strong compatibility and covering a wide range of workpiece inspection scenarios. Owing to its special adoption of APC, ACC driving circuit board design, whatever output power it is selected, it gets perfect protection of itself from overheating and over current, and obtains long serving lifetime. It is suitable for 24-hour continuous operation on industrial production lines, reducing equipment maintenance costs and downtime.
