As the infrared alignment laser dot is invisible to the naked eye, it causes no visual disturbance to on-site operators. In process of continuous dot positioning work, owing to its invisible IR light emission, there is also no glaring visible light to disturb on-site operations, eliminating visible light interference for light sensitive workpieces.
Cooperated with a qualified glass coated lens and adjustable focus optic lens, once TTL modulation laser diode module gets highly concentrated and powerful infrared light, it is forming into a clear infrared reference dot, ideal for high precision single dot marking with excellent positioning repeatability. There is minimal interference from ambient workshop lighting on the 980nm infrared laser dot, ensures stable detection even in complex industrial lighting environments. When infrared alignment laser is operating with basic obeying of potential thermal energy hurt to eyes, after proper wearing of laser safety goggles, it enables secured and precise IR dot indication for automated assembly stations, machine tool alignment, semiconductor component positioning, and robot vision guidance etc.
