Re: Arctic: Spyder III: Review
Dave, for how long can you run it before feeling it getting warm?

I and i think most people were waiting for someone with experience with lasers to get and review the Arctic. This Review was done great and answered the important question.

:thinking: what do you think that Dave knows nothing or has only been doing this a couple days ?
Where do you get that from my comment? That wasn't what i was aplying i was saying that He Has Experience with laser and iam glad that Finaly someone "Dave" with experience got it and reviewed it.. Did i write it wrong?

I did divergence test with my homemade 445nm laser pointer that uses glass lens for red lasers and here are results..
In your picture I can see that dot is about 30mm at 30ft and that is almost 3mRad (I don't know what is beam diameter at aperture)
Is divergence really that bad?
That is what I was afraid of..... that arctic doesn't use correction optics.Not that bad. There is a lot of "blaze" in the photo. The length of the line is about 24mm. The divergence on the fast axis is about 2mRad. It is smaller on the slow axis As I said, it is about what we see with the AixiZ 445nm glass lens.
I did NOT fiddle with the focus.
Peace,
dave
Dave I didn't want to confuse anybody and put a pic of my lens in your thread, so jump back over to the thread I made early this morning; my lens is different than yours, has the same yellowish tint to it.

Dave I'm not sure as I have been mostly been busy with family stuff and I simply haven't tried that yet. I did find a video on youtube that has the same lens I have, if you like I can post the link or send it to you in a PM; I'm trying not to clutter up your thread.
