Works now .. so basically it tells you you can use javascript to do a calc ? I thought I will be able to create the calc to be hosted on that server ..
Somehow the other thread posted to 'general' instead of OT, where it should have been. Couldn't delete it, so I made a new one here.
But yes, essentially I'd like to make a big collection of javascript calculators, one that could be downloaded for offline use by anyone. I figured making it a collaborative project would help get things done faster.
The computed divergence is theoretical, no one says your laser must meet it. Near distance is distance, at which the beam is as thick as at aperture. It can be focused thinner on distances smaller than this.
I'd like to add safe distance estimates, but I don't know the norms. Somebody has a link at hand ?
