LaVision’s StrainMaster systems provide turnkey imaging solutions for various materials testing applications. The systems include all necessary components: high resolution digital cameras from 2 - 50 MP, illumination units, synchronization electronics, mounting mechanics and software for recording and DIC computation.
The StrainMaster Portable hardware offers unparalleled flexibility and excellent stability in a compact package. Building on customer feedback and our experience of DIC use in the field, we have developed the StrainMaster Portable hardware. A typical system comes with a sturdy tripod, flexible gearheads, camera(s), LED illumination units and the Device Control Unit (DCU) X with integrated AD converter.
The StrainMaster Compact is a compact, pre-configured system for optical deformation and fracture analysis. The system works according to the digital image correlation (DIC) method and consists of two cameras and an integrated LED illumination source in a handy measuring head. The StrainMaster Compact is designed for a fixed working distance of approx. 25 cm. Versions with 12 or 16 mm focal length are available with either 2 or 5 megapixel camera resolutions. For data acquisition and evaluation the StrainMaster Compact uses a Device Control Unit (DCU) X - a compact controller unit for all connected peripherals and installed DaVis or StrainMaster DIC software package.
Understanding the mechanical and material behavior of microscale components is extremely challenging and there is often a lack of detailed information on microelectronic or biomedical materials in terms of stress-strain behavior. LaVision offers stereo microscope based 3D DIC systems with special optical calibration models which allow the user to collect and analyze full field shape and strain in sub millimeter ranges. This information is extremely valuable in validating complex Finite Element simulations.
We work closely with the well known microscope manufacturers to offer the best solution for your requirements. A range of manual and motorized microscope bodies are available with varying zoom ratios. Together with carefully selected lenses and specialized adapters we can tailor the system to your particular application, taking into account important factors such as working distance. We have a recommended frame for our microscopes and can supply automated traverse systems for easy controllable repositioning of the system.
Understanding of strain rate effects on material behavior is important in the case of structures subject to dynamic, shock, impact or blast loading. Fullfield data-rich imaging techniques are used to provide a better understanding of composite, metal, and plastic material characteristics at high strain rates. High-Speed StrainMaster systems feature fully integrated high-speed cameras with kHz frame rates.
