  • Compact and lightweight, just 1.5 kg
  • Short working distance, less than 3 mm
  • Superb optical access, up to 110 degrees in reflectance in two orthogonal directions
  • Measurement-ready, via 10-pin electrical wiring to the sample
  • Supplied with a MercuryiTC temperature controller
  • 1 year standard warranty

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-R “cold unit” is interchangeable between the MicrostatHe 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: 1.5 kg
