Date Announced: 11 Dec 2025
Photron, a global leader in high-speed imaging solutions, is proud to announce the launch of the RHEO-Iris high-speed polarization imaging system, developed in collaboration with long-term partners Photonic Lattice of Sendai in Japan have formed a strategic alliance with Anton Paar, a leading global manufacturer of high-precision analytical and process measuring instruments, to create the RHEO-Iris high-speed polarization imaging system. The RHEO-Iris can dynamically measure the retardation and phase angle of birefringent materials, such as wormlike micellar fluids, simultaneously recording the evolution of viscoelastic properties and microstructural orientation of materials on the Anton Paar MCR rheometers.
Available as both an accessory for new MCR’s, or as an ‘add-on’ to existing customer systems, the RHEO-Iris utilizes the Photron Crysta PI-5WP high-speed polarization camera which enables the measurement of two-dimensional refractive index difference and orientation angle with a single exposure at speeds of up to 250 full frames per second (fps), while enabling exploration of microstructural changes in soft matter, including transient relaxation phenomena and shear-induced phase transitions, etc. At the recent Society of Rheology annual meeting Photron demonstrated an Anton Paar MCR rheometer fitted with the latest generation of the RHEO-Iris system. This new upgrade includes several major improvements, including a new full field reflection mode. Unlike our standard transmission mode, the optional reflection mode enables us to image the entire sample under test across the whole 25mm diameter of the rheometer’s upper geometry, it also permits utilization of Anton Paar's Convection Temperature Device (CTD) instead of the standard Peltier heating and cooling system. The CTD provides controlled heating and cooling for rheological measurements across a wide range of temperatures, from -160 °C to +1000 °C.
Reflection mode also enables us to employ rotational synchronization which synchronizes the timing of the rheometer’s data acquisition with image acquisition by CRYSTA. This means we are not just continuously recording until we have filled the camera’s available memory, now we can synchronize our capture rate to the acquisition rate of the rheometer, greatly extending the maximum test duration, enabling you to record long running experiments with ease.
We will also have a selection of Photonic Lattice’s photonic crystal polarizing optical components that includes custom polarizers and phase plates, half-mirrors for laser cavity and true-zero order waveplates and ultraviolet polarizers, among others.
Plus, we will be demonstrating the CRYSTA Nova P16, the world’s fastest high-speed polarization camera, with 16,000 full resolution frames per second (fps), 128GB of onboard memory, unmatched light sensitivity (ISO 64,000), and Gig-E connectivity. This camera performs as both a high-performance 'conventional' monochrome high-speed camera AND the fastest 2D polarization camera in the world.
