When engineers and professionals are trying to make ultra clear and precise cross line projection in 3D vision systems, no matter pointing at close or long distance, it would always make a good job for them to apply a high density light emitted tool of a 850nm infrared cross line laser module. It applies a 850nm near infrared laser diode and a qualified optic lens inside a high duration metal housing tube. Cooperated with an external electric power source and basic thermal emitting system design, whatever output power it is selecting, infrared cross laser achieves high level of laser light cycling use, ultra clear, fine and precise two perpendicular infrared lines generation with different dimensions clearly and precisely.
The usual use of a 850nm infrared cross line laser module is in need to make long operating time lasted infrared light emission from the beam aperture. Employed by an import 850nm infrared laser diode within 5mW to 500mW, besides its adoption of different dimension tube design, it also gets sufficient space leaving for inner part of a metal heat sink and APC, ACC driving circuit board. As a result, when 850nm infrared cross laser makes continuous infrared cross line projection within 10 hours per day, it still maintains high level of laser light cycling use, ultra clear, fine and precise infrared vertical and horizontal lines generation at a great distance. Mainstream 3D vision sensors exhibit high sensitivity to 850nm infrared light, resulting in a high signal-to-noise ratio for the cross-line image and a sharp intersection profile, which facilitates algorithmic detection of the cross-line center.
Whatever output power it is selecting, glass coated lens made 850nm infrared cross line laser module emits highly straight and fine infrared cross lines. It is noncontact with any raw material surface. In addition, the laser is invisible to the human eye, preventing visible light reflections on the workpiece surface and ensuring that the operator’s view of the on-site working conditions remains unobstructed. When 850nm infrared alignment laser is selected with correct output power and optic lens fan angle, after its freely adjusted cross line thickness, it allows for increasing accuracy and brightness infrared cross line projection for all measuring fields.
The infrared cross lines emitting from a 850nm infrared cross line laser module is uniform and the intersection point is sharp. Minimal thermal drift during prolonged operation ensures consistent repeatability in the positioning and calibration of the 3D vision system. Featured by ultra compact size tube design, it allows for direct integration into 3D vision cameras and robotic vision modules, which is compatible with various in-line 3D inspection systems. When infrared alignment laser is operating with proper wearing of laser safety goggles and avoiding eye exposure to beam aperture, it assures secured and fine measurement for multiple fields, including automated 3D scanning, robotic 3D vision guidance, and 3D workpiece profile inspection.
