The TTL modulation adjustable focus 445nm blue cross line laser module offers high brightness, anti-reflective properties, and precise orthogonal alignment. It supports TTL on/off modulation for seamless positioning in automated equipment. Featured by clear visibility under strong workshop lighting, it provides high precision and high brightness cross line alignment, applicable for precision machining, tooling calibration, visual inspection, and alignment of lithium battery and medical components.
Key features:
◆ TTL modulation supports 0–100kHz square wave modulation (0V off / 5V, 9V, 12V on) for on/off switching, supporting constant blue vertical and horizontal lines generation, connected to PLCs, industrial control systems, and vision equipment for synchronized start/stop.
◆ 445nm semiconductor blue laser diode and glass coated lens with 10°, 15°, 110°fan angles assure bright blue light emission, reducing glare on highly reflective workpieces such as aluminum, copper, and titanium, providing better visibility than red light in bright workshops.
◆ Adjustable focus optic lens enables concentrated blue light emission, increasing brightness and fineness blue cross line generation for high lighting occasion and long working distance.
◆ Anodized aluminum alloy housing tube with metal heat sink cooling system and APC, ACC driving circuit board provides heat dissipation, over temperature and over current protection, ensuring consistent blue cross line shape even during extended operation.
