Replica Examination

When viewed microscopically under coaxial illumination, Microset replicas have a bright metallic appearance, allowing detail such as microstructure, micro-cracking and pitting to be observed at high magnifications. These characteristics make Microset replication ideal for the assessment of defects on critical engineering surfaces.
Microset replicas can be examined using various techniques including:

Microscopy 
Stereo Macroscopy
3D Infinite Focus Microscopy
Scanning Electron Microscopy
Atomic Force Microscopy
White Light Interferometry
Shadowgraph Measurement
3D Laser Measurement

Microscopy

The high resolution of Microset compounds allows microscopic examination of replicas up to a magnification of X1000.

Metrology

Despite their flexibility when stretched, Microset replicas retain their initial overall geometry and dimensions and are successfully employed for both high accuracy metrology applications and macroscopic measurements.
