Once users are looking for a high efficiency and high precision dot positioning for night version dot positioning fields, it makes a good job to apply a long wavelength made device, such as a 808nm infrared laser diode module. Employed by an import 808nm infrared laser diode and a qualified optic lens inside a durable metal housing tube, unlike the formal infrared laser pointer only used for temporary dot positioning work, it gets even better thermal emitting design and constant power source supply. After its proper equipment with night version device and installation or integration into night version device, this direct diode emission made infrared dot laser alignment enables easy reaching, low power and time consumption dot measurement and positioning results for all laser processing works conveniently.
Basically 808nm infrared laser diode module gets easy connects with an AC/DC adapter, not spending extra time on prior battery power source change, it enables long term lasted infrared light and infrared reference dot projection from beam aperture. It applies an import 808nm infrared laser diode within 5mW to 400mW and 500mW to 1000mW output power, equipped with inner cooling system or separate metal heat sink part for different output power range, this durable anodized aluminum alloy housing tube made infrared laser alignment always gets larger space leaving for tube heat dissipation, increasing stability infrared light and IR dot generation in long term use.
808nm infrared laser light is invisible, eliminating stray light interference with the main laser processing optical path. The infrared dot emitted from a infrared laser diode module has high collimation and strong focusing, with a positioning deviation of <0.03mm, suitable for micro-precision processing scenarios. Basically it is equipped with a qualified glass coated lens, after its projection of high photoelectric ability infrared laser light emission, it also converts into ultra compact size and precise infrared dot projection at greater distance. When infrared dot laser alignment makes easy adjustment of laser beam focus, after its immediate infrared light concentration, it is converted into an increasing accuracy and brightness IR dot projection in distance immediately. Being made with ultra compact size design, this 808nm infrared laser diode module allows for embedded installation in confined spaces such as processing heads and robotic arms. It is supporting continuous or pulsed light output, which can be directly connected to the control system of laser processing equipment without additional debugging. Infrared alignment laser light is unaffected by strong ambient light or backlighting in the workshop. Even in open-air/high-light conditions during laser processing, it maintains clear positioning, avoiding visual positioning failure issues.
Applications in laser processing:
Laser Cutting and Engraving Pre-positioning: Serving as a cutting origin/processing path marker, it precisely marks the starting point and key positioning points before cutting/engraving metal sheets, non-metallic sheets (acrylic, wood), and precision hardware parts. This allows the main laser to quickly align with the processing position, reducing wasted path travel and improving processing efficiency, especially suitable for small-size, multi-point precision cutting scenarios.
Laser Welding Precise Alignment: Integrated into the laser welding machine head, 808nm infrared laser diode module is used for weld start point/weld point positioning and component docking point marking. In the welding of micro-workpieces such as lithium battery tabs, automotive precision parts, and electronic pins, it achieves precise fit between the weld and the welding gun, avoiding incomplete welds and off-center welds, and improving weld yield.
Laser Marking Assisted Positioning: In laser marking of metal parts, plastic parts, and electronic components, it marks the reference point/center point of the marking area, solving the problems of workpiece clamping offset and marking position deviation. It is suitable for small-area marking scenarios such as QR codes, logos, and precision scales, ensuring consistent marking positions.
