"… I was very impressed not to see ANY effect on the coating from shining onto it with up to 3500W of laser power in a 18mm diameter beam! It’s definitely the blackest material I ever saw. Actually it performs even better than the coatings on the power meters I use, which tend to burn in at these power levels…"

"…The samples withstand the cryogenic conditions during measurement without problems. The main advantage of Fractal Black coating for us is the relatively high blackness at low temperatures (10K-50K) of the source of the thermal radiation achieved by small thickness of the coating (thin layer which is 40 times thinner than our epoxy layer) ...

"I was very impressed from your black coating its ability to be very thin and yet good absorber. The black coating of Acktar made a difference in our light targets performance..."
