Tunable Photonic Crystals
Opalux’s tunable photonic crystals are at the heart of all its technologies. Like the opal, a naturally occurring photonic crystal, Opalux’s materials have bright, unique chromatic appearances. But unlike the opal, Opalux’s photonic crystals are tunable and can change their appearance in response to a range of stimuli. Their precise nanostructure can also make them optically variable – their appearance and colour changing when viewed at different angles and under different lighting conditions.
