Now you can do low temperature optical research in a magnet field!

We've taken the standard Cryostation, with all it's stability, and added a 1 Tesla magnetic field with incredible optical access and experiment flexibility. Optical access through the poles, high NA access from the sides, and low working distance access from the top make demanding magneto-optic applications simple to setup. Nano-positioning of the sample is possible inside the magnetic field to make this an even more powerful product!

The Magneto-Optic module inserts magnet poles into two of the optical ports. The pole spacing is adjustable down to 12mm. The magnet poles may have a bore through the core to allow laser illumination of the sample. This preserves optical access from all four sides, as well as the top. The field strength depends on the configuration used. System includes the power supply and water cooling for the magnet.

The Magneto-Optic module has the unique feature that the sample space and poles can be removed from the cryostat and the magnetix system operated without the cryocooler functions.

CRYOSTATION WITH MAGNETO-OPTIC OVERVIEW
USING THE MAGNETO-OPTIC MODULE WITH THE CRYOSTATION

Here are a few features of this new product…

Use exchangeable pole tips for even higher fields, or for specific field requirements.
Integrated lens holder supports a small lens near the sample
Thin radiation windows between the sample and the poles keep the sample below 4 Kelvin
Easily remove magnets and window housing for great sample access during setup
Electromagnet may also be used as an independent stand-alone unit for room temperature measurements separate from the Cryostation
Active magnet cooling system is included, with temperature control and safety interlocks
Use with unipolar or bipolar power supplies

This graph shows the magnetic field strength as a function of spacing and current. The sample housing within the field uses a 12mm pole spacing. The user may remove the inner housing or create a custom housing for the 5mm pole spacing.

The Magneto-Optic module includes all the other features of the standard Cryostation

Unparalleled sample stability in vibration and temperature. Completely automated temperature control. Temperature stability of 10mK peak to peak from 3K to 350K. Vibrational stability of 5nm peak to peak. Remote control via LabVIEW. Easy to use sample space. Cryogen Free operation.
