IR varifocal laser needed

[microbolometer]

Anyone know of an inexpensive 940nm laser with varifocal lens? Wattage? 1/2 mile range is fine. What ever wattage that would be. If not how about just a inexpensive 940nm laser? Or truly invisible ..doesnt have to be 940 I just need to see it with an IR camera and not the naked eye.

Search for laserbtb. They are trusted with good prices. 980nm is what you will want.

Did you also thought about putting an image intensifier (Gen2, preferably Gen3) in front of your camera. Perhaps you can get along without any additional lighting.

As you are asking for high wavelength above 900nm, I asume that the invisibility is critical not for people rather than game because they see further in the infrared than we do.
I've seen a lot of animals flee because of a light the hunter thought it would be invisible.
