Low cryogen consumption: Brings significant benefits in terms of running cost
Quick experiments: A range of sample holders and probes, including liquid cuvettes sample holders and height adjust/rotate probes, are available
Simple: The experimental windows and sample holders can be easily changed
Versatile: A range of window materials are available. Please contact your local sales representative for more information
Superior performance: A dynamic exchange gas model, suitable for low conductivity or high heat load samples, is 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
Versatile: The OptistatCF-V “cold unit” is interchangeable between the MicrostatHe and MicrostatHe-R, enabling a modular set of optical cryostats for huge experimental flexibility
Temperature range: 3.2 to 500 K, may be extended down to 2.2 K
Temperature stability: ± 0.1 K
System may also be run with liquid nitrogen, temperature range: 77 to 500 K
Liquid helium consumption rate at 4.2 K: < 0.45 l/hr
Cool down consumption: 1.3 litre (nominal)
Room Temperature to base temperature: approx. 10 min with pre-cooled transfer siphon
Sample change time: approx. 60 min (sample can be changed with the cryostat cold)
Weight: 2 kg
A typical system consists of:
UV / Visible spectroscopy: Experiments at low temperatures reveal the interaction between the electronic energy levels and vibrational modes in solids.
Infra-red spectroscopy: Low temperature IR spectroscopy is used to measure changes in interatomic vibrational modes as well as other phenomena such as the energy gap in a superconductor below its transition temperature.
Raman spectroscopy: Lower temperatures result in narrower lines associated with the observed Raman excitations.
Photoluminescence: At low temperatures, spectral features are sharper and more intense, thereby increasing the amount of information available.
