Super-resolution microscope stages by PI

original

Physik Instrumente (PI; Auburn, MA) has added two models to its PInano super-resolution (SR) microscope stage series, both of which are equipped with direct-measuring capacitive sensors. The stages include a large aperture to accommodate microscopy accessories such as slide holders, Petri dish holders, etc., as well as a recessed bottom slide mount to allow full rotation of the turret without in and out Z-motion to protect objectives. Additional features include 200 µm XY or XYZ travel, closed-loop control, and ceramic-encapsulated piezo drives.

PRESS RELEASE

SR Microscope Stages are More Stable with Capacitive Feedback

Auburn, MA – PI (Physik Instrumente) LP has added two higher-performance models to its successful PInano™ superresolution (SR) microscope stage series.

Higher Stability and Reduced Noise with Capacitive Sensors, Lower Cost Piezoresistive Models Still Available
The new models are equipped with direct-measuring capacitive sensors. This type of sensor can provide higher linearity and long term stability than the lower cost piezoresistive sensor-equipped stages which are still available. Capacitive sensors are also less sensitive to noise due to a high-frequency measurement principle as opposed to the DC-based sensing technique used in piezoresistive sensors.  The net effect is similar to the higher quality and lower noise on FM radio channels compared to AM radio. 

Bottom Mount Slide Allows Full Turret Rotation, Protects Objectives
The large aperture accommodates microscopy accessories such as slide holders, Petri dish holders, etc.  The recessed bottom slide mount allows full rotation of the turret without in and out Z-motion, protecting valuable objectives from crashing into the stage on turret rotation.

XY and XYZ Models, 200µm Travel / Axis
Both XY and XYZ stages are available. The low profile design of 20 mm (0.8”) facilitates the integration into inverted microscopes from the four major manufacturers Leica, Nikon, Olympus and Zeiss. 

Optional Long-Travel Motorized Microscope Stage
An optional 25x25 mm positioning stage with self-clamping ultrasonic ceramic motors serves as a stable basis for the piezo scanning stage and allows imaging of large samples.  

Image Acquisition Software
The microscope stages are compatible with all major image acquisition software packages such as Micromanager™, Metamorph™, etc.

Features & Advantages

  • Sensor Choice: 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 Sub-Nanometer Precision
  • Bottom Slide Mount for Full Turret Rotation facilitates Integration
  • Many Options: Slide Holders & Petri dish Holders; Motor XY Stage,  Manual Stage
  • Longer Lifetime due to Ceramic Encapsulated Piezo Drives
  • Software Support for Leading Image Acquisition Packages
