Smallest Spot Size for Extra SMALL engravings!<\/h3>\n

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. \u00a0The diode is also smaller, allowing for the small beam.<\/p>\n

This laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink. \u00a0The laser is set in the heat sink with thermally conductive paste. \u00a0The front of the component contains a adjustable high efficiency glass focusing lens for the laser output. \u00a0\u00a0We advise to run the laser at or under 0.6amps, providing about 900mW to 1W of power.\u00a0 We ship it at 0.4 amps and 750mW of output power.\u00a0 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.<\/p>\n
