This high power 400mW infrared laser pointer is invisible laser.However you can see a little red laser dot if it's focused well.The focus is adjustable. It can light a match,burn plastics,even papers.It's the cheapest high power infrared laser in the market.
The shape of the laser dot is not Round, like red laser or green lasers. It's Rectangle！ You may see it when you adjust the focus. However it's a point when well focused. Refer to the pictures below.

This is a small size - high power tool. Quality is good. Very nice feature is the full adjustable focus, from very wide spread to a very narrow point. As an additional lightsource for a night amplification cam, a little bit disturbing is the beam pattern of the square diode.
But i think in this power-class a point-diode isn't makeable. The best of it is the price, lasers from other manufakturers of the same size and output-power cost 3 times more. Im very pleased, and thanks for the good contact and fast replies to my questions.
