Precision Ion Polishing System Gatan PIPS II Model 695 appearance

Overview

The Gatan PIPS II Model 695 Precision Ion Polishing System is a compact bench-top ion milling instrument designed for the final precision thinning and polishing stage of TEM/STEM specimen preparation.

Utilizing dual independently controlled Penning Ion Guns (PIGs) with argon ion beams, it effectively removes mechanical surface damage and produces exceptionally large, clean, electron-transparent areas with high reproducibility.

Features

  • Ultra-Low Energy Ion Milling for Damage Minimization: Accelerating voltage is continuously adjustable from 0.1 to 8.0 keV. Low-energy milling (e.g., 500 eV or 100 eV) during final polishing minimizes amorphous surface damage layers, producing high-quality specimens suitable for atomic-resolution HR-TEM and STEM imaging.
  • Dual Independent Penning Ion Guns (PIGs): Operating angles for both miniature ion guns can be set independently across a range of ±10° (supporting near-0° low-angle milling). Advanced focusing electrodes maintain small beam spot sizes even at low voltages.
  • Rapid Specimen Exchange (Whisperlok Loadlock): The pneumatic Whisperlok airlock mechanism allows safe, specimen exchange and rapid evacuation in under 30 seconds.
  • Contamination-Free Specimen Mounts (DuoPost): Specialized DuoPost specimen mounts eliminate secondary sputtering redeposition from the platform and feature an X-Y manual alignment stage for precise rotation axis centering.
  • AutoTerminator Automated Control: An integrated optical sensor detects sample perforation or light transmission changes to automatically shut off ion beams and rotation.
  • Touchscreen GUI & Multi-Step Recipes: The front color touchscreen display enables easy creation, storage, and execution of multi-step recipes.
