Equipment
Visual Observation Center (VOC)
General:
The VOC at iMdc is equipped with two cutting edge, high-power optical microscopes for specimen preparation and analysis.
Specifications:
- The Nikon MM-400 Measuring Microscope is a "Tool Maker" microscope with 10x-500x magnification for high-precision dimensional measurement and preparation of test specimens as well as examination of fracture surfaces. The microscope is equipped with a 2D 4"x4" translation stage, an external digital position display (?0.0001"), and PC-connectivity for image capturing and analysis.
- The Nikon Eclipse MA-200 is a Metallographic Microscope with 50x-1000x magnification for detailed microstructural and fracture surface analysis. The Eclipse MA-200 offers standard optical features such as dark-field, bright-field, Nomarski filter, and polarized light while featuring the latest LU optics and design from Nikon. Additional software packages from Nikon allow quantitative analysis - automated grain size measurement and area of field calculations for percentage phase determinations.
- The Questar QM-100 Long Distance Traveling Microscope is an in-situ crack observation microscope which allows sub-micron resolution at working distances up to 10 cm. Longer working distances up to 30 cm can be accommodated for larger depths of field or observation inside atmosphere or temperature controlled chambers. The QM-100 allows 3D translational movement and position display, as well as precision encoders for accurate movement of the microscope. This enables repositioning and refocusing during fatigue crack propagation to capture crack growth interactions with microstructural features of the material.
