The latest shots from our photo feeds
is all around us. Sadly, this is not an example of it.
3D rendering of the optics layout.
There's a built-in charger for the battery.
Beam with Expander
A beam shot with a 3x beam expander mounted.
Beam targeting an unfortunate piece of cardboard. There is no beam expander mounted here and the final beam 6m away is about 6mm.
