the next generation of cryogenics for high-resolution microscopy.
At Demcon kryoz we have developed an ultra-low- vibration miniature cryogenic cooler as a OEM-product. This cooler is designed specifically for use in high-resolution microscopy applications, including SEM, FIB and FM.
Its very small size, the ability to maneuver in six degrees of freedom, and a localized cooling- down ability to -175°C, makes it unique.
And all of this without using liquid nitrogen.
- small size
- only the sample area is cryogenically cooled
- virtually vibration-free
- no mechanical moving parts
- no liquid nitrogen
extreme stable temperatures.
Translation-stage interface is at room temperature.
Controllable sample temperature from 300 down to 100 Kelvin.
High temperature stability ±10 mK.
extreme stable position.
Low vibration level ~ 1 nm p2p.
Low drift levels of <3 nm min-1.
Performance testing was done using a TF Helios FIB/SEM/FM with the cryocooler mounted on a 5 DOF manipulation stage.
