Imaging Instruments
The HO-IS-ROS-01 Rheo-Optics Setup is a microscope-based system designed for studying the rheological behaviour and microstructural evolution of materials under controlled shear deformation. The system combines precision motorized positioning with high-resolution digital microscopy for real-time observation of sample behaviour. It features a motorized XY stage with 50 mm × 50 mm travel and a step resolution of 5 µm for precise positioning of the upper glass plate. A motorized Z stage with 25 mm travel and <1 µm step resolution enables precise control of the gap between the plates. The plate gap can be adjusted from 10 µm to 25 mm, providing flexibility for a wide range of experimental configurations. The lower glass plate is mounted on a fixed platform with a tilting stage for alignment and positioning.
The optical system incorporates a high-resolution digital zoom microscope with 0.5X – 5X zoom and manual focusing. LWD Plan Apochromatic 5X and 20X objectives provide total magnifications from 2.5X to 100X. The microscope supports Brightfield and simple polarization observation with both coaxial top illumination and transmitted bottom illumination. A high-brightness 3W white LED provides adjustable transmitted illumination for observing transparent and semi-transparent samples. The system includes a 360° rotatable polarizer for polarization-based optical studies. A 5 MP CMOS camera with 2592 × 1944 pixel resolution and 2.2 µm pixel size provides high-resolution digital imaging. The camera supports image capture through a USB 2.0 interface and provides selectable imaging formats including RAW, BMP, JPG and PNG. The supplied Micro Analyser Pro software provides live viewing, image capture, scale-bar generation, measurements and report generation.
The system enables direct visualization of microstructural changes occurring during controlled deformation of the sample. Its motorized positioning and precision gap control make it suitable for repeatable rheo-optical experiments. An external excitation port is provided after the bottom illumination path for integrating a laser or other optical excitation source in the future. The compact configuration allows optical observation and mechanical sample positioning to be integrated into a single experimental platform. The HO-IS-ROS-01 is suitable for research involving polymers, colloids, suspensions, liquid crystals, soft materials and other samples exhibiting shear-dependent microstructural changes. The system provides a versatile platform for correlating macroscopic deformation with microscopic structural evolution during rheological experiments.
