Detailed Description

The Tescan SEM is developed with electronic lenses and apertures allowing for working distances ranging from 1-100mm which also gives large field of view. This linked with the 3kg weight limit for the stage gives opportunity to investigate large samples and in-situ experimentation (see picoindenter for further details).

The resultant interaction with samples can be observed using a range of detectors; secondary electron, backscatter electron and both in-lens secondary electrons and backscattered electrons. The electronic control of the electron beam also allows simple beam tilting giving small angle stereographic imaging and electron challenging imaging.

Additionally, the system hosts Oxford Instruments EDX detector and asymmetry EBSD detector which can be operated coincidently at 15mm working distance.

The PI88 Picoindenter can be used for a host of specimen testing geometries from standard indentation and pillar test to more novel fracture toughness cantilevers and square section cantilevers.

Tescan SEM

Analytically the system is stable from 2-30 kV and with a maximum of 10 nA.

PI88 Picoindenter

A range of indenter options are available either high load (up to 500 µN) or low load (up to 10 µN). The low load system has Hysitron CMX control giving depth vs hardness/modulus/stiffness measurement.

Additional modules allow for either sample heating (up to 800 °C), tilt & rotation (for combining with EDX/EBSD) or electronic contact measurement.
