Microscope stages

The company’s PInano line of superresolution (SR) microscope stages now include models equipped with direct-measuring capacitive sensors, which can provide higher linearity and long-term stability than piezoresistive sensor-equipped stages.

A recessed bottom slide mount allows full rotation of the turret without in-and-out Z motion, protecting objects from crashing into the stage on turret rotation. Both XY and XYZ stages are available. The low-profile, 20-mm (0.8-in.) design simplifies integration into inverted microscopes. An optional 25 × 25-mm positioning stage with self-clamping ultrasonic ceramic motors serves as a basis for the piezo scanning stage and permits imaging of large samples.

The stages feature high-stability capacitive or lower-cost piezoresistive sensors; 24-bit controller with USB, Ethernet, RS-232 Interface, and analog control; 200-µm XY or XYZ travel, closed-loop control for subnanometer precision.
