Transforming the way the world uses colour
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. Additionally, and unlike natural opal, Opalux’s photonic crystals are tunable so they 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.
Stimuli Responsive Technology
Opalux’s photonic crystal are tunable and changes appearance in response to a variety of stimuli:
Chameleonix™ dramatically changes colour when exposed to electrical charge. It operates at a low voltage and is compatible with RFID and NFC.
Opal-ID is permanently patterned by laser energy. Opal-ID can be used to provide fully personalized colour-shifting images.
Impact (formerly Elastink) changes colour in response to pressure. This colour change can be permanent or reversible with customizable activation pressures.
Imagine changing the colour of (almost)
anything you want.
