Magnetic field up to 5 T, satisfying the majority of spectroscopy applications
Low vibration and drift: typically 4 nm/min
Low sample vibration: <20 nm typical
Short working distance of 8.5 mm 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: convenient continuous operation 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
1 year standard warranty
Versatile: Provides a cryogenic environment (6 K) ideal for sensitive optical and electrical measurements in magnetic field (up to 5 T).
Low cryogen consumption: Brings significant benefits in terms of running cost.
Simple: The experimental windows and sample holders can be easily changed.
Easy to use: A range of window materials are available. Please contact your local sales representative for more information.
Software control: Oxford Instruments electronics products are controllable through the software using RS232, USB (serial emulation), TCP/IP or GPIB interfaces. LabVIEW function libraries and virtual instruments are provided for Oxford Instruments electronics products to allow PC-based control and monitoring. These can be integrated into a complete LabVIEW data acquisition system.
