Peltier-Module for the SEM
This Peltier-Module can be mounted to the SEM stage «like a specimen». A new temperature exchanger geometry inside the module allows rapid temperature changes and precise control within a 1/10°C using the PID-controller, which is part of this package.

Cryo-Module 80 Kelvin
This «Cryo module» can be mounted to the SEM stage «like a large specimen». The temperature exchanger geometry inside the cryostat body, the so-called «whirlpool»-chamber, runs at very low vibration level, and minimum liquid nitrogen consumption. Liquid (or in some applications, gaseous) nitrogen flows through the chamber. Any temperature from room temperature down to 80 Kelvin can be kept constant using the PID-controller, which is part of this package.
Cryo-Stage 5 Kelvin
Heating Module 300° C
Heating Module 500° C
The specimen holder can be made in many individual shapes, usually in form of a depression or “nest” in the middle. Flat specimens or even crucibles can be clamped down with fine tungsten springs. Much care was taken to avoid electrical fields that may affect the SEM image. The vacuum feedthrough flange and mounting hardware and a processor controlled water cooling system are part of the shipment volume.

Heating Module 1050° C
Heating Module 1500° C
This substage (or “module”) for heating experiments (room temperature to 1500° C) was designed also for the use in a “variable pressure” type SEM. It is clamped to the SEM stage like a large specimen. The module is suitable for corrosion experiments, and heating under gas or vapor (for T=<600°C only!). (NO Oxygen, NO Water) As an option, a needle valve at the vacuum feed-through flange allows fine controlled “bleeding” of gas or of vapor into the heating chamber, during the heating process. This small chamber can be closed by a motorized “lid” during the heating experiment to protect the inside of the SEM.
