GENERAL PURPOSE SAMPLE MOUNTS

A series of fixed and adjustable sample mounts, stages, and holders are available in both stock and custom designs. A summary of these options is listed below:

For sample mounting requiring electrical connections, piezo-actuated motion/positioning, or temperature control of the sample, please refer to the various special purpose categories on Stages & Sample Mounting Options. Many of the options below are compatible with these special purpose mounts.

Description

FIXED & ADJUSTABLE MOUNTS

These mounts are compatible with most Cryostation base platforms. Depending on the configuration, these mounts are typically installed directly on the platform, on a spacer, or on a movable stage. These mounts are cooled by either direct contact with the cold plate or via a flexible thermal link if they are mounted on a spacer or a movable stage. Unless noted, these mounts are typically not thermally damped.

Standard General Purpose Adjustable Mount

The standard mount includes a thermally damped post with standard interface bolt pattern that can be mounted vertically or horizontally to position the sample at various distances and angles with respect to any of the windows. Because it mounts directly to the platform or spacer, it is not compatible with stages, add-on modules, or special housings.

Sample Orientation: Top or side windows
Working Distance: Adjustable
Rotation: Manual, 360° in-sample-plane
Optical Access: Reflection, transmission, low working distance
Thermally Damped: Yes
Dimensions

Adjustable Height Mount

The adjustable height mount can be used in the vertical or horizontal orientation to position the sample at various distances from the top or side windows (30-43mm travel range), and it is compatible with stages.

Sample Orientation: Top or side windows
Working Distance: Adjustable
Rotation: N/A
Optical Access: Reflection, low working distance
Thermally Damped: Yes

Fixed Height Mount

The fixed height sample mount is used on top of stages or a platform spacer to position the sample at a fixed position with respect to the top window.

Sample Orientation: Top window
Working Distance: Fixed
Rotation: N/A
Optical Access: Reflection, low working distance
Thermally Damped: Yes

Side Window Transmission Mounts

These mounts include a transmission aperture plate of varying diameters to allow for transmission measurements through the side windows. These mounts are compatible with special “castle” housing extensions to allow for high NA, low working distance optical access from both sides.

Sample Orientation: Side windows
Working Distance: Fixed
Rotation: N/A
Optical Access: Reflection, transmission, low working distance

Castle Mounts

These tall, narrow mounts are used to position the sample within special “castle” housing extensions. These configurations are often used to position the sample between the poles of an external electromagnet or to achieve low working distances from both sides for transmission measurements using external high NA objectives.

Sample Orientation: Side windows
Working Distance: Fixed
Rotation: N/A
Optical Access: Reflection, transmission, low working distance

Magneto-Optic Mounts

These tall, narrow mounts are used to position the sample between the poles of the Magneto-Optic module for polar or transverse orientations with respect to the field. These mounts are compatible with manual and piezo-actuated nanopositioners and stages, or a manual rotation version is also available (shown). The sample mount material can be specified to be non-magnetic for applications involving AC magnetic fields, such as MOKE.

Sample Orientation: Top, side, or magnet-bore windows
Working Distance: Fixed
Rotation:(optional) Manual, 0-68° perpendicular to sample surface
Optical Access: Reflection, transmission

MANUAL STAGES

Manual stages are used in conjunction with spacers and flexible thermal links to provide adjustable positioning of the sample. The rotation stage provides rotation in the z-axis, while the tip/tilt stage provides rotation in the x- and z-axis. These mounts can be combined with other adjustable mounts or installed on piezo-actuated nanopositioners for additional degrees of freedom.

SAMPLE INTERFACE HOLDERS

Sample interface holders are used to position optical fibers or electrical probes near the sample. These independent holders are typically used in conjunction with manual or piezo-actuated stages to provide coarse or fine adjustment. The angle of attack with respect to the sample can be specified in the design stage. Depending on the space available on the platform, multiple holders can be used. The holder and components are cooled by either direct contact with the cold plate or via a flexible thermal link.

Fiber Optic Holders

A fixed bracket mount holds optical fibers in special V-shaped grooves. Felt compression pads safely secure the fibers and serve to thermally lag them at base temperature.
