Product Family Description

  • Designed for Morphological Calibration and Measurement
  • 8 Test Plates of Various Patterns
  • NIST Certified Version Available

Image Analysis Micrometers are ideal for morphological calibration and measurement of two-dimensional shapes. They feature eight test plates in various sizes of circles, squares, lines, and other geometries. Small patterns, featuring diameters as small as 6.25µm, are ideal for image analysis and machine vision systems, whereas larger features, including a 2.5" linear scale and 0.5” diameter circle, are available for macro inspection. Test plates 1-4 correspond to top patterns and 5-8 to bottom patterns from the left to right. Image Analysis Micrometers are available in NIST certified versions which conform to ASTM-E112 requirements with plate 1, 2, and 8 measured and calibrated.
