JEOL Scanning Electron Microscope

The JSM-6060LV is a high-performance scanning electron microscope with a high resolution of 3.0nm. Magnifications of up to 60,000X are possible and elemental chemical analysis (EDS) is available. Both backscatter and secondary electron images are available. The Low Vacuum mode allows for observation of specimens, such as polymers or biological samples that cannot be viewed at high vacuum due to excessive water content or because of a non-conductive surface. The specimen chamber can accommodate a specimen of up to 6-inches in diameter. Standard automated features include auto focus/auto stigmator, auto gun (saturation, bias and alignment), and automatic contrast and brightness. Applications include fracture surfaces, integrated circuits, micro, and nanomachines.

Asylum Atomic Force Microscope

The Atomic Force Microscope (AFM) has been the instrument of choice for three dimensional measurements at the nanometer scale. The MFP-3D Stand Alone (MFP-3D-SA) AFM is sensitive and precise with low noise and includes a complete scientific software environment. The MFP-3D-SA is ideal for many applications including physics, material science, polymers, chemistry, nanolithography, bioscience, and quantitative nanoscale measurements. The MFP-3D has the flexibility to acquire data, analyze it, and make publication-ready graphics. The maximum roughness that can be measured is about 15 microns and the maximum specimen scan area is 90 microns by 90 microns.

Leica Luminescence Stereo Microscope

This Leica MZ 16S Luminescence stereo microscope allows evaluation of fracture surfaces at magnifications up to about 250X with full apochromatic lens. The large depth of field supports assessment of failure initiation. Microstructures can also be evaluated. The full image analysis system attached to the stereo microscope allows quantification of dimensions, locations, and phase analysis. Features include 2 step stereo microscopy, step ratio 3:1 provides 10x and 30x magnification, 100 mm working distance allows easy access to specimens, integrated 10x high eye point eyepieces with FN 20 provide a large field of view, incident and transmitted light, and luminescence allows biological transmission studies.

Olympus Metallograph Microscope

Metallagraphy has grown increasingly complex with more exotic alloys developed for today’s advanced products, requiring new levels of precision and accuracy in metallographic imaging systems. The Olympus PMG 3 is used to assess a material’s microstructure by first polishing and etching the sample in some type of acid. Then, phases, grain boundaries, and other phenomena can be investigated. Magnifications from 20 to 1700X are common on this microscope. The full image analysis system attached to the microscope allows quantification of dimensions, locations, and phase analysis.

Charpy Impact Toughness Tester:

The Charpy impact toughness test measures the energy absorbed by the high strain rate fracture of a standard notched specimen. The specimen is broken by the impact of a heavy pendulum hammer, falling through a fixed distance (constant potential energy) to strike the specimen at a fixed velocity (constant kinetic energy).  Tough materials absorb a lot of energy when fractured and brittle materials absorb very little energy.

LECO Hardness Testers and other instruments

The Hardness Tester from LECO allows a variety of hardness testing by use of various contact tips and loading weights including Brinell, Rockwell, Superficial, etc. Another hardness tester provides Knoop micro hardness trajectories over very small regions. Various other instruments including a tool maker’s microscope and optical microscopes complete the collection allowing a wide range of hardness and microstructure assessment.
