Microstat MO

The MicrostatMO2 is a compact stable cryostat, which provides a cryogenic environment (6 K) ideal for sensitive optical and electrical measurements in magnetic field (up to 5 T). All these advantages in a single cryostat...

Wide sample temperature range from 6 K to 300 K
Magnetic field up to 5 T, satisfying the majority of spectroscopy applications
Low vibration and drift: typically 4 nm/min
Low sample vitration: <20 nm typical
Short working distance of 8.5mm enabling the use of high magnification optics
Can be orientated horizontally or vertically, providing flexibility for setting-up the experiment
Designed for easy integration of optical components on the cryostat top plate
Can be used for reflection and transmission measurements
Minimum downtime: conventient continuous optieration including improved 300 K operation
Quick sample change using a demountable sample holder.  Two options are available: a copper sample platform for lower base temperature or a sapphire platform for optical transmission measurements
System can be cooled using a pressurised liquid helium dewar for convenient operation with minimum vibration. Mounting bracket supplied to clamp the cryostat to the bench, thus reducing vibrations introduced by the transfer tube.
