A Cryofree® optical cryostat for spectroscopy applications providing a temperature-controlled, sample-in-vacuum measurement environment, with sample access via a unique bottom-loading mechanism.
Wide sample temperature range: < 3 K to 300 K
Easy set-up and operation, no liquid cryogens are required
Unique sample loading, reducing time between experiments
The bottom-loading OptistatDry BLV for spectroscopy consists of a compact cryostat with optical access, cooled by a closed-cycle refrigerator. This cryogen free cryostat is capable of cooling samples to helium temperatures without the need for liquid cryogens. This provides significant benefits in terms of ease of use and running costs and enables optical and electrical measurements to be carried out on your samples. It is also very easy to use with the help of our patent pending sample holders, windows, and wiring options.
3 - 300 K temperature range
No liquid cryogens required
Suitable for a wide range of experiments and different spectroscopy techniques
Optical access better than f/1
Measurement-ready via 12 or 20-pin DC wiring to the sample space
Supplied with a MercuryiTC temperature controller
Versatile: Suitable for a wide range of experiments and different spectroscopy techniques. Designed to interface with both imperial (1”) and metric (25 mm) optical benches.
Upgradeable: A wide range of different sample holders, windows and wiring options enable you to customise and upgrade your system as your experimental needs develop.
Fast experiment: Changing samples via the unique sample access port is quick and simple, eliminating the need to remove the cryostat from the optical bench or re-align your optics after each and every sample change.
Cryofree: No liquid cryogens are required.
Ease of use: Only requiring single phase electrical power means the system is easy to install in a standard laboratory environment. Air- or water-cooled compressors are available.
Software: 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.
Temperature range: < 3 K to 300 K
Temperature stability: ± 0.1 K
Vibration: typical RMS displacement of 10 microns at the sample position
Room temperature to base temperature: < 3 hours
Typical cooling power: 0.2 W at 4.2 K
Optical access: 28 mm diameter clear view f1
Dimensions (HxWxD): 635-900 (adjustable) x 240 x 290 mm
Total cryostat weight: 23 kg
Notes:
•The standard cryostat is fitted with 4 optical radial windows and 1 blank axial window
•Base temperature may be reduced by fitting blanks to each of the windows. Radial window blanks are supplied as spares with the system
•The maximum operating temperature will be set accordingly in the MercuryiTC supplied with the system
A typical system comprises of:
