The Cryo-Optic™ Microscope integrates an optical objective into the sample space of the Cryostation for high NA imaging at low temperatures. The vertical mounting scheme was designed for confocal microscopy, with side optical access available to allow the user to see the sample and approximate focus distance. As an add-on module for the Cryostation, the unit provides the same stability, automation, and control found in all Montana Instruments closed-cycle cryostats.
The revolutionary design of the Cryo-Optic eliminates the alignment and drift challenges associated with using high performance optics in a cryogenic setup. Proprietary Cryo-Optic 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 actively controlled to better than 10mK, eliminating the need to refocus after small temperature changes. A backup power supply is provided to ensure performance.
Compatible accessories and add-ons allow users to configure the instrument for unique experimental requirements, including built-in XYZ nanopositioners for site location and focus or an Agile Temperature Sample Mount for rapid temperature control.
