The SYD1230 Red Line Laser Module 650nm 5mW is a 12mm diameter line laser projecting a flat, straight red laser line at a 120° fan angle using an optical glass cylindrical lens, operating from 3V to 5V DC at up to 40mA current draw. The SYD1230 Line Laser Module differs from common dot laser modules — the cylindrical lens spreads the laser beam into a continuous line rather than a point, making it suited for alignment, levelling, edge detection, and 3D scanning applications where a line reference is needed rather than a single point.
The syd1230 laser datasheet, 650nm wavelength falls in the visible red spectrum, and the 5mW output power places this laser module syd1230—visible and bright enough to be clearly seen in normal lighting, but capable of causing eye damage with direct, prolonged exposure, especially if the beam enters the eye directly rather than as a diffuse reflection. The syd1230 12mm line laser module red connects with just two wires — power and ground — and switching it on and off from Arduino requires only a transistor or MOSFET driver if controlling via a digital pin, since most modules draw current beyond safe direct GPIO limits.
the syd1230 12mm 650nm 5mw red laser module 120° line angle means the projected line width increases with distance from the laser — for precise measurement applications like laser triangulation 3D scanning, the projection distance and resulting line width must be accounted for in the measurement algorithm. Available at StemVolt, this module is well-suited for students and makers working on automation, positioning, and embedded optics projects using reliable 650nm red laser line projection.
