Smallest Spot Size for Extra SMALL engravings!
This is the smallest spot size laser we sell, so you can do the highest resolution engravings or cut with the smallest kerf width. It is a 405nm multi transverse mode laser with small line width, which means that the beam can be focused better than the other 445nm lasers. The diode is also smaller, allowing for the small beam.
This laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink. The laser is set in the heat sink with thermally conductive paste. The front of the component contains a adjustable high efficiency glass focusing lens for the laser output. We advise to run the laser at or under 0.6amps, providing about 900mW to 1W of power. We ship it at 0.4 amps and 750mW of output power. While the mounting case provides heat sinking capability for the laser diode, it is up to the consumer to make sure the laser is operating effectively within these limits.
