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-Detect changes colour in response to environmental conditions. It can be activated by targeted chemicals, biochemicals, liquids or gases.
Opal-ID is permanently patterned by laser energy. Opal-ID can be used to provide fully personalized colour-shifting images.
Impact 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.
