This weekend I did a lot of research on Red Light Therapy for my traumatic brain injury (and fine lines on my face). Anyone else into that?

HCFs for UV need to have VERY thin glass structures, which makes them difficult to fabricate. We are essentially making very long glass bubbles in a 2000degree furnace, and hoping to make perfect, symmetrical tubular walls of a few 100 #nanometers thick! It is a challenge!
