Rotation Stage to Study Anisotropic Samples
The rotation or θ stage allows the automated 360° rotation of the sample, and is useful for characterization of complex anisotropic samples and liquid crystals.
Specifications:
- 150 mm diameter
- Resolution: 0.005°
Maintenance and replacement:
- Mechanical Components: Regularly inspect the mechanical components, such as the motor, gears, and bearings, for signs of wear, misalignment, or damage. Smooth operation is essential for precise rotation and accurate measurements.
- Electrical Connections: Check all electrical connections, including cables and connectors, for signs of wear, corrosion, or loose connections. Secure connections are necessary to maintain communication between the rotation stage and the Uvisel Plus control system.
- Surface Condition: Ensure that the sample platform and other contact surfaces are clean and free from scratches, debris, or residues that could affect the positioning or stability of the sample during rotation.
-
Rotation Accuracy: Periodically test the rotation accuracy and precision of the stage by rotating the sample through known angles and verifying the positioning using the instrument's software. Ensure that the rotation is smooth and that the stage accurately returns to the starting position.
Signs of Replacement:
- Mechanical Wear: If you observe significant wear on the mechanical components (e.g., gears grinding, motor stalling), or if the stage no longer rotates smoothly or accurately, it may be time to replace the rotation stage.
- Electrical Failures: Persistent issues with electrical connections, such as intermittent operation, signal loss, or failure to communicate with the Uvisel Plus instrument, could indicate the need for replacement.
- Calibration Drift: If the stage consistently fails to hold calibration or returns inaccurate positioning despite recalibration efforts, this could be a sign that the internal components are wearing out.
