Transmission Electron Microscope(TEM) Holder
Adopting Peltier modules as temperature control elements, observation without mechanical vibration is realized.
Wide range of temperature is supported: cooling up to -20 ℃ (*) and heating up to + 100℃. Our flexible customization (e.g. sample electrodes) offers environment for in-situ observation of various devices.
* The minimum temperature depends on the ambient temperature, since the heat is exhausted through natural air cooling.
- Large radiating fins mounted on the rear handle of the holder enables sample temperature of -20 C only with natural air cooling.
NOTE: During cooling, the holder insertion port cover on TEM has to be kept open for letting heat dissipate from the fins.
- The sample mounting part is themally insulated from the surrounding parts, and connected to the heat transfer parts via soft foil. This structure enables observation with very little drift
after the temperature is stabilized.
- We offer flexible customization such as electrodes for the sample. Along with temperature control, other functions could be combined, for example:
• Sample transfer in the air shut-off state
• 3-dimensional probe drive
* Measurement example in a room with temperature controlled at 23℃.
"Rear handle" refers to the part where the heat dissipating fins are attached.
