An image supplement to the Wicked Lasers 445nm <1W Spyder III Pro Arctic Series Series thread.
I would ask that this thread be restricted to specific and constructive conversation and contributions of beam shots and videos. The thread is intended to provide a critical analysis of this specific laser product and its components. There will be no banter or speculation about laws, dangers, burning things, and other uses or mis-uses of lasers. Moderator has permission to delete off-topic posts.

Wicked lasers appears to have uploaded a video to YouTube demonstrating their newest product. Hundreds of orders have been taken, none of them have been filled yet that we know about.

I have created a gallery of snap shots from this video. Stills are much easier to ponder over and analyze, so for your convenience I've included a few of them below.
So far so good. These are the first images we're getting from this product in actual use, albeit coming from the manufacturer themselves. Since no orders have been filled yet, this is all we get for now.
There's a bit of concern and speculation over whether the dot will be a clean circle. The animation above shows a scaled comparison of the dot viewed through filtered safety glasses, verses the dot in full bloom.
The oval appearance is definitely caused, at least in part, by the sideways perspective of the camera. It is really hard to say whether it is purely circular when viewed from straight on.
I'm also concerned about the amount of side spill, or presence of "zing zing" (spill from a single direction). These video stills reveal a bit of what appears to be sidweays spill, but it's hard to tell how much of this is actually just the camera's CCD overloading.
As seen from an earlier angle, almost straight on.
Considering that the main attention of the beam is being absorbed by a black material intended to absorb laser light, which is set about an inch off the wall, we have to assume the light hitting the wall is actually "zing", and not camera optic flaring from the center dot. I believe what we see hitting the wall must be an emission coming all the way from the laser module sitting on the table.

For anyone who acquires this laser, or builds one of their own from the same diode, please post pictures here.
We are interested in close up details of the dot shape and size-over-distance (divergence). When taking pictures, try having the camera pointed in straight perspective to the wall, and not from a sideways angle. Please measure and mark and include every detail. Please try taking photos of a filtered dot from 1 meter away and 100 meters away, on a target that includes scale/ruler. The camera should be as close to the filtered dot as possible while in focus.

so I can take pictures once I get a better lens if you want... I'm pretty sure there are some threads at LPF that have close up dot-shots.
Of course others saw, but most didn't.
