The fastest measurement and inspection of coronary and endovascular stents

Sierra VDI has all of the stent measurement capabilities of the Sierra Dimensional system. Also, it can detect functional and cosmetic defects over the entire outer diameter of coronary and endovascular stents—not just selected locations.

Capture form and surface defects both as-cut and after polish

Catch critical defects with ESI's production-tested defect detection technology. Detect form defects with or without CAD data. Detect surface cosmetic defects using our patented illumination designed specifically for electropolished metal surfaces. FineScan advantages include:

  • Uses line-scan and area-scan cameras to capture crisp images
  • Multiple general purposes and vector processes for image analysis
  • Detailed part review window with zoom and rotate capabilities

Get the scale, reliability, innovation, and price needed to meet next-generation production requirements

  • Morphological algorithms offer quick setup and instant coverage of 100% of the outer diameter of the stent.
  • FineFit CAD comparison finds deviation from the stent design—even after electropolishing.
  • Measure stents as long as 200 mm with the extended length option—recommended for endovascular users.
  • Increase throughput and accuracy with auto-opening chuck.
