Imaging software adds automatic measurement and coating thickness evaluation

Olympus Europa Holding : 17 November, 2013  (New Product)
Olympus launches the latest version of its workflow-orientated materials science imaging software, Stream 1.9, which introduces dedicated functions to streamline specific tasks including automatic measurement and coating thickness evaluation.
Imaging software adds automatic measurement and coating thickness evaluation
The software is able to make advanced analysis and reporting options fast and simple regardless of user expertise, offering step-by-step guidance for each task. Olympus Stream 1.9 covers the control of the microscope, cameras and accessories, image acquisition and processing, measurement and analysis, as well as report generation and data management. 
 
For easy integration, the software now offers full Windows 8 and Microsoft Office compatibility. This valuable capability allows the export of tables and graphs into Microsoft Excel for statistical analysis, as well as the use of Microsoft Word and PowerPoint for the generation of professional reports and presentations. 
 
Flexibility and future-proofing are key features with four expandable packages available: Start, Basics, Essentials and Motion, allowing users to create and grow their system to suit individual requirements and future applications.
 
As an operating system for a range of Olympus microscopes, including both upright systems (such as the BX51) and stereomicroscopes (such as the SZX10), the software includes new predefined measurement and analysis options.
 
For example, because thickness is the most important variable affecting coating quality, the new dedicated Coating Thickness function determines thickness quickly and easily using the rapid and reliable Calotest method (also known as the Ball Crater method). The Calotest provides a quick, simple and inexpensive determination of coating thicknesses. A rotating sphere, with a known diameter is pressed on the coating surface with a preselected load. Both the position of the sphere relative to the sample and the contact load are constant. Upon adding abrasive slurry to the contact zone, a depression with the shape of a spherical cap is abraded into both the coating and the substrate.
 
Optical inspection of the depression reveals the projected surfaces of the abraded coating and substrate sections. By measuring key dimensions, the thickness of the coating can be calcuted by a simple geometrical equation.
 
The fast Automatic Measurement function for edge-detection-based measurements using pattern recognition is able to perform multiple measurements in a single live image, greatly improving efficiency. This includes a validation tool that provides a pass/fail flag for every measurement.
 
All in all, Stream 1.9 contains more than 50 measurement and analysis functions based on the most up-to-date standards. For quality assessment of steel and cast iron, the dedicated Cast Iron function measures graphite nodularity by size, shape and distribution, with results automatically generated according to international standards.
