The Lens focus is adjustable, not fixed, can adjust to an appropriate spot size, and then fix it.
Three-wire input, the red line is positive, black line is negative, TTL signal yellow line is positive
Features:
The 980nm Laser is invisible, but can be seen by 980nm display board, it will be displayed as a green dot on the board.
.
This 980nm laser module with driver built-in is an industrial electronic component and used for Industrial testament, Lab.
Working Voltage 5.0V, red wire for 5V+, black wire commonly for 5V- and also for TTL -, Yellow wire for TTL +.
If
you only connect its black wire and red wire, the laser would not work,
you also need to connect its yellow wire (TTL+) to 5v+.
