Beamshots of <0.1mW violet

[Zom-B]

Tonight I was playing with my adjustable PHR. I tried to project the image of the chip on the other side of the room, so I set the power to really weak. I was surprised that I could still see the beam with my bare eyes! (and luckily with the camera too). I tried to measure the power, but the meter didn't even register it in the 0.1mW resolution range. I guess it's still below or just at the threshold current.

It looks dimmer to the eye! (16 seconds exposure)
