What is a good job for engineers and professionals to make ultra clear and fine line indication in those of laser cutting works, not able to rely on any prior line drawing or printing work, it would be an efficient job to apply a long wavelength made device of a 808nm infrared line laser module for those of night version illumination fields. It is projecting 808nm invisible IR laser light, which does not interfere with the human eye or visible light vision inspection equipment. When it gets constant electric power source supply, not relying on any professional skills, after correct use of output power and optic lens fan angle, this laser line generator makes no visible mark residue, no mistake and noncontact IR line indication for stealth cutting and processing of sensitive materials.
Basically 808nm infrared line laser module applies a qualified glass coated lens within 10 to 110 degree fan angles, equipped with an import 808nm infrared laser diode within 5mW to 1000mW, it enables high penetration and highly powerful infrared laser light source generation at different work distances, low attenuation in dust, smoke, and oil, resisting strong workshop light and electromagnetic interference, with stability superior to visible light sources. It belongs to an industrial-grade module, which can withstand a wide temperature range of -20~60℃ and vibration of 10-2000Hz, suitable for outdoor and heavy-duty processing environments.
When 808nm infrared laser line generator projects highly straight and fine infrared reference line within 0.5 meter to 6 meters length in distance, cooperated with adjustable focus optic lens design, it always enables excellent straightness of the line, positioning accuracy reaches sub-millimeter level. Infrared laser line fineness can be adjusted freely so as to get ideal line alignment accuracy onto different cutting raw material surfaces. When it achieves required cutting width, it can significantly improve bath processing consistency. After the adoption of 16mm, 18.9mm and 26mm diameter tube design for different output power range, this infrared line laser module can be easily installed in confined spaces,achieving high electro-optical conversion efficiency, low power consumption, continuous working life **≥12000 hours.
Applications in laser cutting works:
Cutting Path Positioning Marking: 808nm infrared line laser module projects a reference linear line onto fiber/CO₂ cutting machines and plasma cutting machines, covering the entire cutting line in one pass. It is suitable for cutting metal sheets, PCBs, woodworking, and acrylic.
Machining Tool Setting and Focus Calibration: Used for tool/nozzle height calibration and focus position setting in CNC and laser welding machines, suitable for multi-layer cutting of thick plates and contour tool setting of irregularly shaped parts, improving first-piece yield.
Online Visual Inspection Guidance: 808nm infrared alignment laser is used as a line structured light source to assist in the detection of part dimensions, edge burrs, and cut perpendicularity after cutting, applicable for semiconductor silicon wafer scribing and photovoltaic cell crack detection.
Invisible Pre-marking and Heat-Sensitive Processing: Pre-marking cutting lines on materials such as photoresist, thin glass, and flexible circuit boards without damaging the substrate.
Multilayer Material Alignment and Stacking Cutting: Provides interlayer alignment references for composite materials, multilayer PCBs, and thin film stacking, reducing waste caused by layer misalignment.
