Coating for Optical Applications
AR Coating for Plastics
 For various plastic substrates, such as PMMA, PC, PET and TAC --- the substrates that are utilized for front panel on LCD or other display --- NIDEK provides highly visible Anti-Reflection coating (AR coating) with high transmittance, for minimizing reflection glare.
NIDEK's AR coating technology features our own in-house developed vacuum deposition method; the quality is among the finest available in the optical thin film industry.
(The optical and physical properties presented below are the values of AR coating for acrylic substrates.)
