Superconducting magnet systems
Please contact Lake Shore if you are interested in a superconducting magnet system.
| Model | Sample environment | Operating temperature | Magnetic field | Optical access | |
| Cryogen-free systems | DryMag | Vacuum/UHV or exchange gas | 1.5 K to 700 K | 0 to 12 T | Yes |
| He-4 systems | SuperVariMag | Flowing helium vapor or vacuum/UHV | 1.5 K to 325 K (options to 400 K) | 6 to 12 T | No |
| OptiMag | Flowing helium vapor or vacuum/UHV | 1.5 K to 325 K | 6 to 12 T | Yes | |
| SuperOptiMag | Flowing helium vapor or vacuum/UHV | 1.5 K to 325 K | 7 T | Yes | |
| Room temperature bore systems* | Atmospheric pressure or vacuum/UHV | 300 K | 6 to 12 T | Yes | |
| Special systems | Microscopy | Vacuum/UHV | 3.5 K to 450 K | 0 to 7 T | Yes |
| Vector magnets (contact us for more information) |
Vacuum or helium vapor/liquid | 1.5 K to 800 K | 5 to 12 T | Yes | |
*Room temperature bore systems can be combined with variable temperature cryostats to operate in temperature ranges between 1.5 K and 800 K.
