FEI Quanta 200 ESEM with Gatan MONOCL3 System

The FEI Quanta 200 Environmental Scanning Electron Microscope (ESEM) is a thermal tungsten gun instrument capable of imaging under three vacuum regimes, High-vacuum (< 6e-4 Pa), Low-vacuum (10 - 130 Pa) and ESEM-vacuum (10 - 2600 Pa). It is capable of SE imaging at the following resolutions for the given settings:

The Quanta is equipped with a Gatan MONOCL3 system for acquiring cathodoluminescence spectra and images. It has a Czerny Turner monochromator with a Peltier cooled Hamamatsu R943-02 PMT UV-Vis detector and a liquid nitrogen cooled Hamamatsu R-5509-72 PMT IR detector. A Gatan C1002 liquid nitrogen cold stage is available for cooling samples to 80 K while a Gatan CF302 continuous flow liquid helium cold stage is available for cooling to 5 K. A Melles Griot HeCd 100 mW dual wavelength laser is available for simultaneous PL studies with excitation at 325 and 442 nm.

Kleindiek micromanipulators can also be fitted to this microscope.
