Dimple Grinder Model 656 appearance

Overview

The Gatan Precision Dimple Grinder Model 656-3 is a mechanical pre-polishing instrument designed to produce a spherical dimple in the center of Φ3 mm TEM specimen discs prior to final ion beam milling.

It significantly reduces final ion milling duration (e.g. PIPS) while maintaining a robust outer rim for specimen handling and yielding a central area thinned to a few micrometers without thermal or structural damage.

Features

  • Precision Depth Control: Real-time digital depth indicator with automatic shut-off when the pre-selected dimple depth is reached.
  • Adjustable Specimen Load: Precise load adjustment mechanism protects fragile semiconductors, single crystals, and composite materials from cracking.
  • Versatile Grinding & Polishing Wheels: Compatible with diamond grinding wheels for rapid material removal and felt/bronze wheels with diamond paste for final mirror polishing.
  • Transmitted Light Optical Inspection: Transmitted light illumination allows monitoring of specimen light transparency and fringe patterns to determine thickness.
