De uitdaging
The consumer-electronics company required a broadband anti-reflective coating stack achieving residual reflectance below 0.15% across the visible spectrum. The solution had to be PFAS-free and compatible with their existing substrate portfolio (PET, PC, PMMA, TAC).
02
Onze aanpak
Kriya designed a multi-layer AR stack utilising the full RI platform from 1.16 to 1.95. The stack was optimised through optical modelling and validated on four substrates, measuring transmission gain, haze, reflection, pencil hardness, and adhesion per ISO and ASTM standards.
03
Het resultaat
Broadband residual reflectance below 0.15% was achieved on the multi-layer stack. Transmission gains ranged from 2.2% (PMMA) to 3.3% (PET), with 100% adhesion on all substrates. Pencil hardness varied by substrate from HB (PC) to 4H (PMMA). All formulations were PFAS-free.
Waarom Kriya
Kriya offers the widest PFAS-free RI range (1.16–2.00) from a single supplier, enabling complete multi-layer AR stacks without sourcing from multiple vendors.
