Peltier module for SEM

"

Temperature range -25°C to +50°C / Extended version, temperature range -50°C to +100°C.

Precise and rapid temperature control

The Peltier module fits into an SEM chamber like a large sample. The included PID controller and the design of the module geometry allow precise and rapid temperature control (1/10°C).
Quick connectors for water circulation allow the module to be assembled and disassembled in seconds.

Thanks to its unique internal design, sample current measurements can be carried out while the module is heating or cooling.

The module is designed to accommodate standard SEM holders, crucibles or a spring clip system to hold the sample on the cold (or hot) surface.
The module can be integrated into an SEM or SEM/FIB.

Temperature controller

The integrated PID (or manual) controller allows temperature control up to 80K. The controller takes into account all the heating and cooling parameters and can be used after an initial learning routine.

A continuous hot/cold ramp can be selected to study (when working towards +100°C) the sample at a constant heating/cooling rate. The built-in heater can also be used to achieve temperatures between the cold of liquid nitrogen and ambient temperature. The controller will take over the cooling setpoint up to the required temperature without oscillations. The manual module can be controlled by the user to achieve the desired temperature.

Integration of the module in the SEM

The system is mounted in the SEM as a large sample using a dovetail system. It is possible to tilt the module in the chamber.

Cold module

The dimensions of the module are 100 x 60 x 30 mm. The central heating element is fitted with a multi-layer thermal protection shield. The contact surface is minimised to keep temperature transfer between the sample and the module structure at a very low level.
Various sample fixing systems are available.

The Peltier module reaches temperatures in the range -25°C to +50°C and the extended version from -50°C to +100°C.
