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. 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.
Stimuli Responsive Technology
Opalux’s photonic crystal are tunable and changes appearance in response to a variety of stimuli:
Chameleonix™ changes colour when exposed to electrical charge. It operates at a low voltage and is compatible with RFID and NFC.
Opal-Detect responds to the presence or absence of compounds in the environment. It can visually identify 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 to secure identification documents against counterfeiting.
Impact changes colour in response to mechanical force or pressure. This colour change can be permanent or reversible, with customizable activation pressure.
Imagine changing the colour of (almost)
anything you want.
