I'd bet my left nut the divergence is magnitudes worse. NcStar is not exactly know for high end gear. Their stuff is best suited to airsoft warriors and mall ninjas.

I remember studying flow cytometry in immunology, a course I took back in the 1990s. There are all sorts of uses for lasers that most people never hear about.
^^^This.
Lasers are our future, the best EM source human has created so far. We might look for new uses and developnent of the hobby IMO.

Not only lasers, but even LED's. Those blood oxymeters they clip on your finger to measure oxygen saturation levels work by shining a red and infrared led through your tissue, and calculate oxygenation levels from the signal losses between the two.

If some procedure uses a laser to create an effect it's often mentioned because it sounds cool, but if there is something even cooler involved the laser is quickly forgotten.

This like lasers are also used for pretty mundane tasks as keeping track of someones position in a MRI scanner. And that thing should actually be called a NMRI scanner, but the word 'nuclear' seems to send patients running from hospitals... which in in itself is a decent triage tool :D

I had access to NMRs in Chemistry years ago. I've known for at least that long why MRIs are not called NMRs. They do both work on the same concept. Neither of which has anything to do with radioactivity.
