Optistat CF
- Temperature range: 3.4 - 300 K. May be extended up to 500 K with the high-temperature window option and extended down to 2.2 K when used with a rotary pump (not supplied as standard)
- Cooling to 4.2 K in about 25 minutes
- Short sample change time via a top-loading sample probe - as quick as 5 minutes
- Low liquid helium consumption: <0.55 L/h when used with a low-loss transfer siphon
- Configured for reflectance and transmission measurements
- Superb optical access for measurements requiring light collection
- Large illumination area: 15 mm diameter window aperture
- Compact size allowing easy integration into commercial spectrometers
- Measurement-ready, via 10-pin electrical wiring to the sample
- Supplied with a MercuryiTC temperature controlle
Features:
- 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

A typical system comprises of:
- Cryostat
- Sample holder
- Spectroscopy windows
- MercuryiTC temperature controller
Applications:
- 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.
