Fischione Model 200 TEM Prep Dimple Grinder
A dimpling grinder for TEM specimen preparation. It thins the center of 3 mm discs to just a few microns using a rotating wheel and abrasive slurry, preparing samples for final ion milling.
System Capabilities
The Model 200 thins the center of a disk specimen to create a dimple suitable for final thinning. It can be used for single- or double-sided dimpling with precise depth control.
The dimpled region is typically finished by ion milling to achieve electron transparency.
Operating Modes
Single-Sided Dimpling
Thin one side to form a central dimple.
Double-Sided Dimpling
Optional for symmetric thinning and reduced stress.
Depth Control
Fine control to stop at target thickness.
Final Ion Milling
Prepare for electron-transparent finishing.
