- Cryogen-free operation – Avoid the expense, hassle, and supply challenges of LHe.
Models & Options
CryoAdvance
CryoAdvance takes the next step in advanced materials and quantum device characterization. Extremely low vibrations at the sample allow challenging applications such as microscopy, cavities, and opto-mechanics. The system can be easily placed on the optical table just as any other optical component, making it easy to enhance existing setups. Free-space optical access through five optical windows provides high flexibility. The CryoAdvance can be tailored to individual requirements by a wide set of options. DC, RF, fiber, or gas feedthroughs can be installed together with options for magnetic field and high NA microscopy. Many different housing styles and sample holders are available.

Cryo-Optic
Seamlessly integrate a microscope objective into your CryoAdvance or Cryostation! Cryo-Optic provides ultra-stable, high-quality, high NA imaging at low temperatures. Proprietary technology allows the objective to be held at room temperature within the sample space for highly stabilized position and focus control. The temperature of the high magnification objective and the sample are controlled to better than 10 mK, eliminating the need to refocus after small temperature changes. This allows you to drastically reduce the time required to reach a stable measurement condition by isolating the objective from both the cryostat and the laboratory environments.
Features
- Eliminates alignment and drift challenges – no more issues associated with using high performance optics in a cryogenic setup.
- Configurable for experiments – includes built-in XYZ nanopositioners or an Agile Temperature Sample Mount.
- Vertical mounting scheme – designed for confocal microscopy, with side optical access to see sample, and approximate focus distance.
- Vacuum compatible – Cryo-Optic add-on includes a special vacuum compatible version of a Zeiss Epiplan Objective.

Magneto-Optic
Add magnetic fields to your cryostat with the Magneto-Optic option. This module integrates a magnetic field directly into the cryogenic sample chamber. Magneto-Optic applications are simple to setup, with unique designs to preserve full sample and optical access. Automatic zero function removes any field stored in the iron poles by using an alternating decreasing field to degauss the poles and effectively eliminate the field when the magnet is off. Systems include a hall probe calibration fixture, power supply, water cooling for the magnet, and Montana Instrument's built-in Galaxy software.
Features
- Variable configuration of field strength – depending on configuration used, various pole spacing and pole tip options are available.
- Top optical access port – can be configured with a recessed objective for low working distance applications.
- Compatible accessories and add-ons – allows configuration for unique requirements, including optional built-in piezo stages for sample motion.
- Adjustable radiation shield – accommodates setups, allowing users to expand or resize the sample space or make adjustments to allow for more optical access options.
