A comment on LEDs may cause retinal toxicity at occupational domestic illuminance.
This pulse laser was so powerful that at discharge through the microscope it could create a white spark in mid-air; the
so-called waist area.
I Hired on to CooperVision as a Developmental Tech, I inadvertantly grounded a flash-circuit while the laser exit face
aligned to my eyes.
The Fluke Meter actually bounced a centimeter into the air at discharge, and I saw a moderate orange glow for a bare
instant.
Immediately after, and today, when I gaze into a clear blue sky, I see a "small dounut shadow" of two to three degrees
in my mid to lower right field.
The contrast of the Donut image has decreased over the years but decades later, I see it. What do you Know? I got shot with a surgical welder.
-No worries though, No worries at all.
