A 4 K helium-flow, sample-in-vacuum cryostat system designed for optical microscopy.
3.2 K - 500 K temperature range
Quick cool-down time and low helium consumption
Short working distance
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
Versatile: The MicrostatHe “cold unit” is interchangeable between the MicrostatHe-R and OptistatCF-V 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 at 4.2 K: < 0.45 l/hr
Cool down consumption: 1.3 litres (nominal)
Room temperature to base temperature: approx. 10 minutes with pre-cooled transfer siphon
Cryostat weight: 1.8 kg
A typical system comprises of:
Micro-FTIR: Study of molecular bonds in crystal lattices
Micro-Raman Scattering and inelastic light scattering: Study of molecular energy levels
Micro-luminescence: Studies of Quantum Dot structures in AS/GaHS
Micro-Photoluminescence / Micro-Photoluminescence: Study of semiconductors
Micro-luminescence: Quantum systems, dots/wires/wells
