Laser marker transmissivity in polycarbonate sheet
Laser marker transmissivity in polycarbonate sheet
(OP)
I'm involved with setting up a laser marker station that will mark 6mm thick polycarbonate sheet. The laser is 1064nm wavelength, 10W power. Axis of laser is perpendicular to broad surface of the sheet. The laser focus point is inside the 6mm sheet thickness dimension, not on either upper or lower surface.
Area around the focal point will be shrouded for safety. The management is concerned that the PC sheet material will act as a lightpipe and transmit laser radiation out of the edges. I say, at 10W, not enough to worry about due to attenuation and dissipation. And if it does, then we can put simple blocking barriers around the periphery of the sheet to limit any exiting radiation.
The marker vendor has no idea.
Any thoughts?

RE: Laser marker transmissivity in polycarbonate sheet
Your ENTIRE setup should have been enclosed and interlocked. This is not a trivial matter.
I'm terrified that your company is willy-nilly using these lasers without a qualified laser safety officer (LSO). Get one, and get one NOW!!
Your company has opened itself to serious liability issues, and you should not be counting on the beneficence of internet strangers to answer laser safety questions.

My question is whether or not anyone has any insight into the suspected lightpiping phenomenon of PC sheet.
