3D Optical Microscopic Strain Measurement System

The HAYTHAM Optical Microscopic Strain Measurement System is a non-contact strain measurement system based on binocular 3D or monocular 2D DIC technology. Combined with a high-precision stereomicroscope or metallurgical microscope and an in-situ loading stage or heating and cooling stage, the system captures images of microscopic specimens during loading at the micrometer scale. The software processes the acquired images and outputs measurement results in real time. 


● Application Fields: Biomaterials, semiconductor materials, electronic products, composite materials

Application Cases

Wire tensile testingMicroscopic strain
Tensile Test of Biomaterial Wire

In biomaterials research, tensile testing of wire is an important experimental method for evaluating mechanical properties such as elastic modulus, yield strength, and fracture toughness. These tests demand extremely high accuracy, especially when handling micro-scale or nano-scale wires, where even tiny measurement errors can affect the results.

In-situ tensile testingMicroscopic strain
In-Situ Tensile Test of Plant Fiber

In a study of in-situ tensile testing of plant fiber, the research team used the Haytham visual microscopic strain measurement system to analyze the mechanical properties of the fiber in detail. During the test, the system recorded the deformation of the fiber in real time and generated full-field strain results, giving researchers reliable data on its mechanical behavior.

High/Low Temperature Deformation Test of Phone Optical Sensor

In the high and low temperature deformation test of a phone optical sensor, the sensor must withstand extreme temperature changes from 20°C down to -40°C and back up to 200°C. To ensure stable performance under these temperature conditions, its deformation must be measured precisely, and non-contact DIC delivers accurate full-field data throughout the thermal cycle.

Shear-Tensile Microscopic DIC Test of Welded Titanium Specimen

In microscopic shear-tensile testing of welded titanium, weld zone and base metal differ markedly, and strain concentrates near the weld nugget, heat-affected zone, or interface. Traditional extensometers and macroscopic methods cannot resolve these local details. Microscopic DIC captures full-field strain at high magnification, revealing local deformation clearly.
