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:
Electrical Activation
Chameleonix™ changes colour when exposed to electrical charge. It operates at a low voltage and is compatible with RFID and NFC.
Chemical Activation
Opal-Detect responds to the presence or absence of compounds in the environment. It can visually identify targeted chemicals, biochemicals, liquids or gases.
Laser Activation
OpalPrint is permanently patterned by laser energy creating multi-colour, colour-shifting designs, and images.
Mechanical Activation
Impact changes colour in response to mechanical force or pressure. This colour change can be permanent or reversible, with customizable activation pressure.
