Got a bunch of gear in the mail this week:
laser safety goggles, tuned to the 808nm infrared of the cutting laser. Here is the spec sheet. These are model EP-5, so they have OD3. OD5 is ideal for the power range we are working in, but OD3 is INSUFFICIENT better than nothing. To be on the safe side, I plan to only operate the power lasers in an opaque enclosure.
A variety of lenses for shaping the beam path.
Tiny Tiny beam splitter.
An finally the new geared motor for the new pinch pulley extruder, with the perfect timing belt pulley on it’s end.
