Customer Testimonials
"… 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…"
David Toebaert - E.L.A.S. NV
"…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) ... "
Tomas Kralik - ISI Brno
"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..."
